Summary: Rio Del Lago 100 starts and finishes at Beal’s Point, at Folsom Lake State Recreation Area in the Sierra-Nevada Foothills. It consists of 2 lollipops that both have out and back sections but loops at the “end” of each out and back, and it runs on much of the same course as the American River 50 and the Way Too Cool 50k. The course features a variety of terrain, from single track trail, to fire roads, to paved bike path.

Lessons Learned from Race Reports

Daylight Savings Time occurs during the race but the race will observe the time from Saturday and will not change the time
No trekking poles
With the first 19 miles being on a paved bike path, it’s easy to go out too fast and burn out your legs
Elevation gain seems tame but it’s scrunched in the middle ~37 miles, so actually quite challenging
A lot of people ended up running into the cutoffs throughout the night and were surprised by how much slower they moved at night, especially on the challenging ascents.
Have crew ready to be there much earlier than expected in those early miles because they tend to be fast
Heats up quickly during the day
Many people didn’t take the elevation gain seriously because it’s so tame for a 100, but it’s really 13.5k of gain in 37 miles, which is quite challenging, and much of those miles are heading into the night and throughout.
