review of 2017 Delaware Marathon.   

5 / 5 Stars


I generally liked the course, consisting of two loops with plenty of changes of scenery to keep your mind occupied.

Race Tips

Two loops with a slight incline at mile 25. There are a lot of half and relay runners. Really good finisher village, lots of vendors and food.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

The Westin in Wilmington provided a shuttle to the start.

review of 2013 Delaware Marathon.   

5 / 5 Stars


Very nice race and certainly worth doing once. Very well run. The race starts on the riverfront in Wilmington, takes you through downtown and along the Brandywine River, through the parks, and into some of the neighborhoods of Wilmington. Its a great way to see the city. Being from the area I know the city pretty well, and I think the race highlights the best parts of it. Be ready though because there are hills....the big one we call .."Monkey Hill." Its long and gradual. But be prepared to recover on the return down hill. My only knock is that it's a two loop course. I personally don't like 2 loops and it means you have to run those hills twice. But all that said.....its worth doing, at least once. There is a half, and 4-person and 8-person relays, so it has the feel of a bigger race than the actual number of marathoners. The after party is good.....good food, good drink. There is plenty of parking around the start so you shouldn't have far to walk. The expo is not bad, but this is not a huge race so don't expect something of that size. The medal and shirt in '13 were very nice.

Race Tips

Weather should be near perfect at that time of year. Review the course map and be prepared for the hills. There is also a pretty brutal hill at the end of the course that takes you through the center of the city, be prepared for it. Enjoy the shade through the park and the stately neighborhoods.....and none around little Italy. Fan support is pretty good. The aid stations are well stocked and manned by great volunteers.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

Plenty of hotels in the area....look in the neighboring towns, Newark and off route 202, for cheaper deals if you don't want to stay in town. Plenty of parking in and around the start but arrive early so you can find your way to the start. If you are flying....go into Philly, unless you can get a much better deal out of Baltimore. Plenty of great options for restaurants in the city and outskirts.
