I’ve kind of factored altitude in by training on some higher climbs, but not quite above 1,500m (more around 1,000 to 1,500m).
For background, I’ve listened to some TR and other podcasts on the subject (thanks for the pointer, in any case). While I know roughly where my W/KG should be for the duration, I also know that I’ll really have to be conscious of my power as we get into the higher parts of the course.
Next race after this will be a race up part of Mount Fuji in June (similar kind of distance and elevation gain), which mirrors a race I did back in 2015.
Ride With GPS course gives an idea of what’s in store for the race this Sunday...
