Trail Quake Half Marathon, 10K/5K

Trail Quake Half Marathon, 10K/5K takes place on May 9, 2027, in Saratoga, California. All three races start together at 7:30 a.m.: the half marathon over 21.6 km (13.4 mi), the 10K (6.7 mi) and the 5K (3.2 mi). No elevation gain is listed.

A common start for three distances means a crowded opening mile and a field that thins quickly, so resist the pace the 5K runners set around you if you are there for the half. All three distances measure slightly long, which is normal on trails: run by effort and by elapsed time rather than expecting the markers to match your usual splits.
