Location
Parc de Miribel-Jonage, Vaulx-en-Velin (Lyon), France
A run, then a mountain bike, then another run. Cross Duath'Lyon packs three disciplines into one short off-road blast: 4km run, 11km MTB, 2km run. Format S is done in roughly an hour.
It runs at Parc de Miribel-Jonage, Lyon's big outdoor park on the eastern edge of the city. Forest paths and lakeside tracks for the runs, proper MTB trails for the bike leg. Early October, 09:30 start.
The fastest cyclist rarely wins here. It rewards handling under load, a clean transition and legs that can run hard off the bike. Skill across all three beats raw power in any one.
Who this suits
- Runners who can handle a bike. A strong 5km runner who rides confidently on trails has close to the perfect profile for this.
- All-rounders who like variety over specialism. Three disciplines in an hour rewards range, not one big engine.
- Riders comfortable on singletrack under pressure. The MTB leg asks for clean handling while your heart rate is pinned.
- Athletes wanting a short, sharp local race. Around an hour on Lyon's doorstep, no long-course commitment.
Training plan
A training plan for Cross Duath'Lyon isn't a generic base build. Beina reads the event's exact demands, looks at your specific profile and the time you actually have, and maps a highly adapted plan to the start line.
01 · Race demands
Three sports, one hour
- A 4km opening run, long enough to bury you if you go out too hard
- 11km of MTB trail at threshold, steering the bike while your heart rate is pinned
- A 2km closing run on brick legs, the hardest 2km you will run all year
- Two transitions, where 30 to 60 seconds is real podium time
02 · Key sessions
What your weeks look like
- Run intervals like 5x800m at 5km pace and 4x1km at 10km pace for economy
- MTB threshold work: 3x10min at 95-100% FTP, plus an all-out 11km time trial
- A weekly brick, building to a full race-pace mock of run, bike, run
- Dedicated T1 and T2 drills until each transition is under 30 seconds
03 · Shaped around you
Not a generic schedule
- Built from your current fitness and the time you actually have
- Adapts every week as Beina learns how you respond
- Syncs your sessions straight to Garmin and Wahoo
