Overview
Register early for the Black Toenail Friday Half Marathon & 7.5 Miler—this popular autumn tradition often sells out, organizers warn. It’s a lot more fun than spending the day at the mall!
You’ll burn off your Thanksgiving indulgences without having to hustle to the starting line. The generous 11:00 AM start time for both races allows you to take your holiday weekend slow.
Both races are run on the well-groomed trails of Proud Lake State Recreation Area. The half marathon course is composed of two loops. (Those running the 7.5 Miler will break off before the second loop to race back to the finish line.)
The half marathon course features less than 300 feet of elevation change throughout the event, offering runners all the beauty of a trail race without grueling climbs. Expect ample course support, as well, with four water stops that runners will loop by twice, for a total of 8 opportunities for water, Gatorade, and gels.
Course Description
This two loop course not only offers great views, on great running trails, but is also flat with only 250 feet of elevation gain over the entire half marathon course. Athletes will be treated to aid at 6 different locations. All turns are marked with turn signs, taped off trails and hanging tape. If this is you’re a race or your first time trail running this course is perfect for you!
