Choosing % FTP for long climbs

[QuittingBikes]

I’m doing a similar ride, the Tour de Big Bear, next weekend on Saturday, Aug 7.

2022 Tour de Big Bear 100 mile

The two big climbs are both in the back half of the course, so the goal is to conserve energy in the first half. Taking elevation into account, I’m shooting for an IF of 0.65 in the first half and 0.70 in the 2nd half.

Target pacing for the big climbs, which are 1,587 ft @ 4% and 2,084ft @ 4.7%, will be around 65-75% FTP. My LTHR is in the low 160s, so I’ll be paying attention to HR as well, trying to keep it below 150-155. May have to adjust on the fly based on RPE.

Also bringing four 2.5 oz bottles of pickle juice in case I cramp. I’ll let you know how it goes.

How To Pace Z2 at Elevation?

I’m signed up for the Tour de Big Bear. The 100mi ride is mostly spent around 7,000 ft. I’ll be plenty happy if I can hit an IF of 0.70. How does elevation affect Z2? Does it have the same effect on Z2 as it does at Z4+, or is it less pronounced? I live at sea level. [Screen Shot 2021-07-27 at 9.10.47 PM]
