Don’t think they do them. September trip is usually a bit of a training camp so nice to see the numbers and track tss accurately. I can recreate some of this years HCs too to gauge race pace.
Fair enough. Remember off-road is more demanding than on-road for the same recorded TSS though - your whole body gets done over (unless you're on Champagne Gravel™) so the actual training stress is higher.
If you're hiring, can't you get them to fit a powermeter? Also, why? If you're hiring a bike I presume it's a holiday rather than competitive...
