Badger Cove Half Marathon, 10K & 5K

Badger Cove Half Marathon, 10K & 5K is held in Fremont, California, on April 17, 2027, with all three distances starting at 7:30 a.m. The courses run on the scenic trails around Lake Del Valle, where the climbing tests even seasoned athletes. The 5K is relatively flat and suits anyone wanting to hold speed, while the 10K and the half marathon (13.1 miles) take on hillier ground and a harder day's work. Runners get solid on-course support and a lively trail running community, and the half counts towards the Brazen Ultra Half Series.

Trail hills change the maths: run to effort rather than to pace, and expect a half here to take noticeably longer than your road time. Two months of weekly hill work, plus practice walking the steepest sections on purpose, is the preparation that pays.
