Welcome to the Central Illinois Summer Trail Series! The 1st race in this series will take place at Kinsey Park in Peoria, IL. It is following the 4.16 mile trail loop that is used in the
"Yellowbrick Backyard Ultra" that is hosted on the course the very next day by Sophie Russell (If you've never heard of a backyard--- you should check it out!)! This is a great way to get exposure to trails, and also learn a little bit about the local ultramarathon community.
The course offers hills, plenty of runnable sections, and some Wizard of Oz themed stretches to bring some joy to the grind! Elevation gain for this loop is approximately 240’.

The Central Illinois Summer Trail Series wraps up its first season in epic fashion at Farmdale Reservoir—a premier Central Illinois destination for trail running, mountain biking, and hiking, and the
legendary home of the annual Farmdale Endurance Trail Runs (including the grueling 30-, 50-, and 100-mile ultras)!
With approximately 15 miles of diverse, well-maintained trails—including fast open stretches, tight twisty singletrack, fun gravity dips, ravines, meandering paths through prairie and woods, and a perfect mix of technical challenges and flow—this spot is built for adventure and has tested countless runners over the years.
Come close out the series strong, toe the line with the area's top trail talent, see where you stack up, and celebrate completing the full Summer Trail journey on one of the region's most iconic courses!
