Enjoy a post-race beer and a bowl of chili. Grab a spot on the sunny grass or utilitize the shade of the shelter while you bask in the glow of your trail accomplishment.
Age group awards for the 10 Mile will be announced around 10:45am, while the marathoners are still on course.
Awards for the Marathon, including finisher shirts, will be announced a little bit after Noon.
The 10 Mile course will be run on the Sag Valley Trail. The entire course is wide horsetrail, with little to no technical trail running required. ***Please be aware that there are usually horses on the course***
The challenging part is the hills – with 670 ft of elevation, this 10 miler is ‘mountainous’ by Chicago standards.
Each turnaround point features an aid station, at these approximate mile marks: 3, 5, 8. There will be a porta-potty at mile 5.

Please carpool! The parking lot at Teason’s Woods (11200 S Willow Springs Rd) only holds 50 cars. Please carpool.
We have been told that if we tell you to park in another lot, we pay another reservation fee…
But just so you know, there is another lot @ Saganashkee Slough – East (10901 S Willow Springs Rd). You could theoretically park there and walk 400m south on the Cal-Sag path to Teason’s Woods.
We have been asked not to have you park near the Swallow Cliff stairs & then do your 1km warm-up jog west to Teason’s Woods. But we can’t stop you from doing either of those.
We also cannot stop you from parking at Cherry Hill Woods and doing a 1km warm-up jog south through the woods.
We always need volunteers, and we reward our volunteers with swag or discounts. If or your group would like to volunteer with us, please email info@f3running.com
