The Next Loop Endurance Series
THE NEXT LOOP ENDURANCE SERIES
The format is simple: one trail loop every hour.
Complete the loop, return to Race HQ, recover, refuel, and get ready to go again at the top of the next hour.
Run one loop. Run five. Run ten and reach 50K territory. Keep going as long as you want.
There is no DNF in The Next Loop. Every completed loop counts.
This format is designed for everyone from runners taking their first step into trail and endurance running to experienced ultrarunners looking for a new challenge.
You control your day. You control your distance.
