Boulderthon Half Marathon Training Program

Join our 12-week half marathon training program! We safely build speed and endurance to help you achieve your goals, whether they are to complete the distance or to set a personal best. We host road workouts tailored to every experience level, and our group long runs provide the community and motivation you need!

This program is perfect for runners who have run a 5k or 10k and want to tackle a longer distance, and for runners who have completed 13.1 miles and who want to build their speed and finish faster than before. We recommend being able to run 4 miles before starting this program.
