6.5W/kg

An estimated ~416 W held for ~36 min (big mountain endurance + sweet spot).

The winning move
7.9W/kg · final 1 km

A second straight Alpe d'Huez day after a three-hour stage, so the climb is an even more fatigue-limited, controlled tempo. The win still comes from a ~2.5 min kick over the final kilometer at roughly ~505 W.

Today's ride: 195 min · long ride with Crescendo Climbing Intervals: Croix de Fer, Telegraphe, Galibier, Sarenne, Alpe finale
CoachCat, build me a 195-minute long mountain ride for today modeled on Tour de France Stage 20 over the Croix de Fer, Telegraphe, Galibier, and Sarenne to Alpe d'Huez. Give me Crescendo Climbing Intervals, each proportional to how long the climb takes: 24 min Sweet Spot for the Croix de Fer; 13 min Threshold for the Telegraphe; 19 min for the Galibier as a crescendo of 13 min Sweet Spot into 3 min 30 seconds Threshold into 2 min of Zone 5 into a 30-second Zone 6 summit; 14 min for the Sarenne as a crescendo of 9 min 30 seconds Sweet Spot into 2 min 30 seconds Threshold into 90 seconds of Zone 5 into a 30-second Zone 6 summit; then long endurance and a final 4 min effort for the last ramp to Alpe d'Huez: 3 min 50 seconds of Zone 5 into a 10-second all-out sprint to the line. Make it my long ride of the week, scaled to my FTP, current LEVEL and OTS, and tell me how to pace it.

What that workout looks like (Croix de Fer 24 min Sweet Spot · Telegraphe 13 min Threshold · Galibier 19 min crescendo · Sarenne 14 min crescendo · Alpe finale 4 min Zone 5 → 10-second sprint):
