Hill SprintsSpeed You Can Keep
Mix short, explosive hill reps with steady Z2 trail loops to raise your ceiling and keep speed between obstacles. We teach efficient uphill lean, quick-feet downhill, and pacing you can actually hold on race day. Fully scalable by hill length and reps.
Hills, Trails, and Pacing— Engine Work on Real Terrain
Develop uphill power and downhill agility while holding a steady aerobic rhythm. Sessions balance intensity with recovery so you finish strong instead of fading late. Suitable for all levels with clear scaling and terrain options.
How often should Ido hill sprints?
Start with 1 session per week, keeping reps short (10–20 s) with full walk-down recovery to protect hamstrings and maintain quality. As you adapt, add 1–2 reps or a second short hill set, but keep overall volume modest so your legs stay fresh for longer aerobic work.
What shoes work beston your trails?
Choose trail shoes with dependable lugs for grip and a moderate stack height for stability on uneven ground. In wet conditions, prioritize a stickier rubber compound and consider locking the heel with your laces to prevent slide on descents.
Will sprints ruin my endurance base?
No—when paired with Z2 trail repeats, short hill sprints raise your power ceiling without eroding aerobic capacity. Keep the sprint portion brief and high-quality, then return to steady Z2 pacing to train fast recoveries between obstacles—exactly what you need on race day.
