Fantastic Event

Full Review:

Full disclosure, I've only participated in 4 half/full marathon events - Kansas City, St. Louis, Wichita, and now Champaign, but this was by far the best of any. I'm not really going to get into the expo or post-race events although both were high quality, but the most important aspect - the race - was such a good experience. The course was marked exceptionally well, including signs at every intersection and volunteers galore; there was zero chance of getting off course. The water/gatorade stations were well placed and there were plenty of them. Everyone was super helpful and friendly. The course difficulty as described on this site is accurate. It's not pancake flat but it is a great course to BQ on. Any hills are very subtle and never last long. Even the hill at mile 24 which is the only real hill in the entire race is over in a little over 1/4 mile and it followed by a nice downhill to finish off the race. All of the turns were reasonable; the only small quip I had was when you run through the park the trail weaves a bit making it a little more difficult but this is a very small complaint.

Race Tips:

Don't worry at all about the mile 24 hill. I think I let it get in my head and held back a bit leading up to it, then had more energy for the last mile than expected. While that sounds great on the surface, I would rather have cut 10-15 seconds a mile during 23-25 and let 26 take care of itself with it being downhill.

Flat and fast

Full Review:

Small but not so small race (1,000 people running the full, around 3,000 running the half). Good support in terms of volunteers and hydration, and completely flat.

The start was very easy and well organized, 6 different waves, lots of porta potties (but of course they still had long lines). No security hassles, and lots of parking around.

Sparse support from the crowd (Probably due to being a college town on a saturday at 7am), not enough fast pacers (Fastest was 3:15, 3:05 got injured).

Race Tips:

Small hill around mile 24, not all hydration points are separated by the same distance so it might be something to consider. Even pace/effort seems to be the best bet.

Travel/Logistics Tips:

Stayed at the Illini Union, close to the start/finish, and my family was able to easily spot me at miles 1.5, 12, and then they drove to 19. They then parked near the stadium and waited for me inside to see me finish.

FUN, FUN, FUN

Full Review:

I am NOT a runner, BUT I love this 5k! There are so many great runs that our whole family and friends find and event just right for them! Every detail is taken care of and they have the coolest metals!!! Love the bands and music along the way!

Race Tips:

Expect tons of support along the route!

Travel/Logistics Tips:

There is ample parking and the courses are well planned

Full Review:

Great support and great course

Full Review:

Great support and great course. Almost completely flat with just a few very minor hills. Friendly and supportive crew.

Race Tips:

My strategy was to run with the 3:50 pacer so I could BQ but that turned out to be unwise for a couple reasons. I really needed to start slower and more conservatively so I would have energy at the end. If you read my Erie Marathon review you will see I changed strategy and went with the slower pacer and it made all the difference in the end.

Be sure to wait outside the corral until you are absolutely sure you have peed all you need to pee! I made the mistake of getting in too early and then having to stop at mile 6.

Travel/Logistics Tips:

There are plenty of hotels just about 1/2 to 1/4 mile away off campus. It's an easy walk or warm up jog to the start line from the closest hotels. There did seem to be plenty of parking if you are too far to do that.

Well Organized and Easy to Run

Full Review:

The Illinois Marathon is the best run Marathon I have ever run. The pacers are accurate. The housing is abundant. Parking is easy and the after party surroundings are fantastic.

Full Review:

Run with the wind

Race Tips:

Be prepared for any weather conditions. The worst can be the winds or raining with cool temps.

Travel/Logistics Tips:

Follow the directors to avoid traffic jams and being late to the start line.

The fans and community are better than anywhere else in the country. Illini Country can't be beat!

Race Directors are great!

Well run and easy to participate in.

Race Tips:

Well organized, fun and exciting

Full Review:

I like how extremely organized they are. I also love that most of the money goes to well deserving nonprofits.

Race Tips:

Just be ready to have fun.

Travel/Logistics Tips:

Arrive early enough to get a close parking space. There is plenty of parking.

The best race!!!!

Pacers are very positive, plenty of drink stations, & lots of support from the community.

Travel/Logistics Tips:

Hotels are walking distance from start line, & if drive morning of race plenty of parking.

Christie Clinic Review

Full Review:

Excellent course aid in the long races. They had water and gu every 7 miles ish. Plenty of spectators around campustown/downtown Champaign-Urbana. Awesome finish through a tunnel and into Memorial Stadium!

Race Tips:

Prepare for any weather conditions. Late April in Champaign is a mixed bag. Expect to feel great through the first half, but from miles 18-24, it can be pretty lonely. Especially 19-22. Even though the Urbana Country Club seems a long ways from Memorial Stadium, the finish line comes quickly from there.

Travel/Logistics Tips:

Park at the northern side of Assembly Hall on campus, close to the stadium. Have plenty of cold weather gear in your car.

Love Running into Memorial Stadium!!

Full Review:

This is a Great event capped off by finishing in the Memorial Stadium where Red Grange played. That was one of the things that drew me to this event. Then last year the local TV station selected my Cousin Paul and I to be the Face of the race. What a Great event.

Race Tips:

The course is fairly flat which helps having a lower finishing time which helps making a Personal BEST time as I did last year.

Travel/Logistics Tips:

I like the Illinois Marathon and Indy Marathon the best as the starting line is close to shelters where you can warm up/work out to be run ready when the race starts as the starts are usually cold.

Flat Boston qualifier.

Full Review:

God atmosphere. Finish at memorial stadium.

Travel/Logistics Tips:

Arrive Early.

AMAZING

Full Review:

Just awesome

Full Review:

Great all around. Easy access to information. Great porta potties. Well stock and frequent tables.

Race Tips:

Run it. Love it.

Friendly neighborhoods to run through

Full Review:

It's all good. Several live music venues along the way. Friendly neighborhoods to run through and the finish line is inside the stadium.

Fun and Flat

Full Review:

I love the crowd support, the super awesome finishers medals and getting to finish on the Illinois Football Field. But the greatest thing is the course is almost all flat so you can PR!!

Race Tips:

On race expect a lot of fun and a lot of people so patience is key

Travel/Logistics Tips:

For $10.00 you can buy a shower pass to use the athletic center after the race. The greatest $10.00 you will spend, get cleaned up before you head home

Race directors, community, and volunteers.

Nice flat course!

Course is easy to follow.

Travel/Logistics Tips:

Come early for parking!

Smooth easy course

Full Review:

Friendly people urging you on, and the course is pretty level. Champaign-Urbana is scenic in April and is a nice place to visit.

Exciting marathon

Full Review:

Its a rush... Well organization... For my age i feel encourage and welcome!

Race Tips:

I try to set my pace and just work hard to keep it through out, it helps me hip issues.

Travel/Logistics Tips:

I live here so i park south of the start line.

Perfectly Executed Run!

Full Review:

Loved the flat terrain and that everything was run efficiently. Loved crossing the finish line in the Football Stadium at the University of Illinois.

Great Flat Boston Qualifier

Full Review:

Incredible volunteers. very flat and fast course. I PR every time I race here.

Race Tips:

Very flat course. Only congestion point is at 8-10 miles if you are running slower than 2/4 hours pace for half/full. This portion is through a beautiful city park but the path is only about 6 persons wide or less over bridges.

Travel/Logistics Tips:

Make your hotel reservations early. Check the web site for participating hotels and shuttles for morning of race.

Awesome

Full Review:

Hospitality is great, the whole community comes out to tailgate for this race.

My favorite!!!!

Full Review:

The Illinois marathon weekend is the absolute best!!!! Everything from the swag, to the course, the amazing crowd cheering every step of the way, finishing on the football field, great after race food. Its definitely my favorite race.

Race Tips:

The pre race food was great!!! Trying to get in to our corral was a bit frustrating.

Travel/Logistics Tips:

Parking can be a bit tricky. I parked a street over from campus and walked a block or 2.

Great for the newbie or seasoned runner

Full Review:

This marathon is great for the newbie or seasoned runner due to its flat course and well laid out design.

Race Tips:

Flat course and typically on the colder side

Great starter Marathon

Full Review:

The course is mostly flat. I liked finishing in the football stadium.
The helpers are the best.
I didn't like walking up to get out of the stadium.

Race Tips:

You are also running with the Half Marathon Runners. When the Half turns toward the finish it gets a little lonely.

Super fun and flat

Full Review:

The energy in Champaign Urbana is incredible during this race! The volunteers are great and there are so many random people and households along the way to cheer on the runners, it is impossible to not have fun :D

Race Tips:

It's a flat course and a very popular Boston qualifier. Roads are all concrete or asphalt and the Cities do their best to make sure the route is in great shape right before the race.

Travel/Logistics Tips:

If you have a friend in town, stay with them! Otherwise book your hotel early.
We have numerous fabulous restaurants, it's hard to single out any.
There is plenty of parking, just don't wait until the last minute.
Also, don't miss the expo on Thursday and Friday. Give yourself time to check that out.

Epic Race, Amazing organization, Lace up and GO!

Full Review:

This was the first marathon I ever ran, and gosh was it an amazing experience. Not only does the course have an excellent setup, but the volunteers, scenery, music, entertainment, & spectators ensure it will be a positive experience throughout. So much thought, care, and love is put into this race! The directors love to hear and actively work to improve minor things every year! Great post race snacks, too!

Race Tips:

Well marked, with lots of volunteers guiding the path. Great pacing groups that are very reliable! Extremely friendly if you join in late and want to stay with a group throughout the event.

Travel/Logistics Tips:

Champaign-Urbana is a great city for a marathon, located in the heart of IL, robust campus town, has lots of options while still maintaining a small town vibe. Plenty of parking at the event.

Very well organized

Full Review:

This marathon is very well organized. Their miles are marked well, they provide water, Gatorade, and fuel at many stations. The time of the race is nice because at the end of April the weather is usually not hot or cold on race day and you can do your training before the weather gets hot. I love that the whole city gets into the race the weekend of. There are tons of supporters during the race, businesses and even people who live along the race route cater to the runners while we're in town. It makes the race a really fun atmosphere!

Race Tips:

It's a nice, fairly flat course. The race is busy so get there at a good time beforehand and take advantage of all the free stuff at the expo and on the course!

Travel/Logistics Tips:

The Saturday of the race gets very busy so I recommend having a hotel the night before. Be sure to book it several months in advance. I've never had trouble parking the day of, just remember to read your information carefully to know where you can park and plan extra time in case traffic gets backed up.

Good course and good support

Full Review:

Good course and good support

From Subject Received Size info@findmymarathon.com Review from Madness Page: Illinois Marathon 4/5

Full Review:

Although I have not run the full marathon I have run the I-Challenge twice and I love it. It is a pretty flat course but an absolute challenge! I love the flat course but hated the bad weather (which the Race directors have nothing to do with) the two years that I ran it!

Race Tips:

Race day is a thrill, pace yourself for a fast course because there are no real downhill runs to catch up!

Travel/Logistics Tips:

Parking in the Assembly Hall parking lot was more than convenient!

Fast and flat

Full Review:

Great volunteers. Incredible expo. Very fast flat course.

Race Tips:

Expect lots of fans and plenty of racers. Pacers do an excellent job.

Travel/Logistics Tips:

Use the web site when booking hotel rooms some have shuttle service and others do not.

Unforgettable

Full Review:

Excellent environment, cheering and playing music the whole race, and variety of landscapes around Urbana-Champaign

Race Tips:

Super flat and fast race

Perfect size marathon

Full Review:

The venue was great. There was adequate fan support. Absolutely loved the course and finishing in the U of Illinois stadium was great.

Full Review:

Want flat - this is it!

Full Review:

My 1st love of this course is that it is FLAT! No "rolling hills" that usually is someone's lame perception of major incline just to see what you got in the tank. The crowd that comes out along this course is AMAZING - both for the half marathon AND the full. The organization of putting this event on has NEVER been less than AWESOME. ILL....INI! It's the best in the midwest!!

Race Tips:

It's Illinois - and it's April.... so do not go into this race expecting you can predict the weather. BUT the one thing you can count on there is always winds - some years it's been stronger than others. Book your hotel as soon as possible so you can be as close as possible to walk to the start and from the finish. I recommend Hilton Garden Inn - staff has ALWAYS been amazing and they are ready for it being a race weekend.

Travel/Logistics Tips:

Whoops - mentioned this above.

Hilton Garden Inn - have stayed there at least 5 years in a row now - they are VERY accomodating to anyone participating or supporting others who participate in this race. If you don't want to do the event dinner....Nando Milano - AMAZING Italian food for carb loading the night before... on the higher $$$ but worth it. More mainstream - you have Biaggi's, Olive Garden, Fazoli's. Post race - Kofusion or Destihl. For breakfast - The Original Pancake House, get there EARLY or be prepared to wait - it's worth it!

Flat and fast race!

Full Review:

Well managed. Friendly people at the expo and GREAT fans spread across the course.

Race Tips:

It is a very flat course but remember to grab water when you can because some years it is warm.

Flat and great local support!

Full Review:

Full Review:

Super flat course if that's what you're looking for. Excellent fan support. Good sized expo and I got to meet Katherine Switzer! Finishing on the Illini football field is fun. Using the U 0f Illinois campus for expo and race start made parking (free) a breeze. Some bad road conditions especially in the campus and the course while pleasant isn't scenic.

Race Tips:

The course is very flat. A runner should be able to settle into a consistent pace and if the weather cooperate (it did in 2013) a PR can be accomplished here. Plenty of aid stations and 4 gel stops. Every water stop was organized differently unfortunately. Uniformity is so important late in a race when fatigue sets in.

Travel/Logistics Tips:

I camped so I can\'t comment on host hotels but I did take advantage of the shower option after the race in the University recreation center and that was excellent. Plenty of free parking on the stadium parking lots.

Fast course, exciting finish!

Full Review:

I loved the variety of the scenery on the course. Running through campus town of Champaign and through downtown Urbana. Subsequently through the peaceful countryside and ending in the college football stadium. Great place for friends/family to spectate and cheer on their runners.

Race Tips:

The weather can vary greatly. I've run this marathon 4x and been there in cooler weather, damp and super sunny days. So be prepared for different temps.

Travel/Logistics Tips:

I've stayed in both Champaign and Urbana for race weekends. I typically leave a little earlier to ensure I have time to park and stretch before the race. Depending on when you arrive it can be a longer walk to the starting corral. As for hotels, over the years they've been more accommodating to runners, like offering breakfast earlier for runners.
