Intervals.icu can now plot power adjusted for altitude (tx @John_Peters_endura.f ) using the unacclimatised (1-7 days at altitude) and acclimatised (several weeks at altitude) formula from Bassett et al. Here I have plotted power & power adjusted for altitude (acclimatised and not) on Alpe D’Huez. I didn’t pace it quite as badly as I thought!
