The paved trail along both sides of the Fox Valley River is very flat.

The inauguration spring version of Last Chance BQ.2 has the perfect running weather, 40-50 with no or little wind. A small well organized race with friendly staffs.

Race Tips

The course is flat 8 loops around a lake which helps mentally since you know what's coming for the rest of the race once you run the first loop. If you like a flat course and try to BQ, this is the race for you. But I found out the hard way that my legs don't respond well with super flat course, they cramped up at mile 14 and multiple times along the way. I pushed on and still PRed but did not BQ, missed it by seconds. Elite bottle table was nice so you can drink anything you've trained with without having to carry it the whole way. There are two additional water stations beside the elite bottle table so you basically have access to water almost every mile. Pacer for my group ran a bit fast for first half but not significantly faster. Paramedics on course are very attentive, if they spot runners in distress they will approach by running along side you and check if you are doing ok. I was in a really bad place for my last loop, Joanna (paramedic) approached and ran with me the whole final loop, encouraging and checking on my conditions. My legs gave out a few hundred yards before the finish line causing me to miss my BQ. But overall, a great race and excellent staffs!

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

Race is in the park near downtown St Charles which has plenty of good restaurants to choose from. I went to Giordano's, not for deep dish pizza but simple spaghetti with marinara sauce. Good size portion and tasted great! Get there early so it's not too crowded since it's Friday evening. I went there at 5 pm and there were plenty of tables, by the time I left at 6:15 they were all filled up.
