ways to prep for the Mammoth Trail Fest

Here are a few dedicated workouts and one training plan to get you prepared for the race day.

  • This plan is designed to increase your ability to sustain higher intensities on hilly and technical terrain. It focuses on longer days out at low/moderate intensities and contains a 2-block buildup without taper time but is highly specific to a wide variety of mountain projects. Athletes should be prepared for six running days up to 80km (50miles) weekly. Access to hilly terrain is mandatory.
