TrainHybrd Podcast - Hyrox, Hybrid Training, Running & Endurance 082: Getting Faster Without Getting Injured (For Runners & Hybrid Athletes)
9 snips
Mar 26, 2026 They explain what speed actually means for sprinters versus endurance athletes and why event context changes training. The role of muscle fiber types and how hybrid fibers suit mixed-intensity races gets explored. Practical tools like zone 2 work, strides, threshold and VO2 approaches are discussed. They also cover load management, low‑impact cross‑training and how consistency beats sporadic hard sessions.

Episode notes
Speed Depends On Event And Energy System
- Speed depends on the event: sprinters train maximum velocity and anaerobic power while 10K/Hyrox athletes train aerobic speed and threshold.
- Context matters because top-end sprint speeds (~40 km/h) are irrelevant for typical endurance paces (~16 km/h) and energy systems differ.
Build A Big Aerobic Base First
- Prioritise a large aerobic base (Zone 2) and only add one hard session per week when time-limited.
- Jackson recommends most weekly training under 80% max HR and a single threshold/VO2 session for progress and recovery.
Hybrid Fibers Drive Hyrox And Mixed Races
- Muscle fiber mix determines race demands: Type I for repeatable endurance, Type IIx for max power, Type IIa hybrid for mixed efforts like Hyrox.
- Hyrox and hilly races rely heavily on IIa fibres for repeatable surges and power endurance.
