“Hard start, easy once the break went” was what Henderson noted after the stage and he was right. In the first hour of the stage, Henderson set his peak power values from 60 seconds to 60 minutes! His 60-second Peak Power was 512 watts (7.3 w/kg), 60-minute Peak Power was 301 watts (3.3 w/kg).

Energy burned: Henderson has burned approximately 42,339 calories in the Tour to date!

First hour: 299 average watts (4.3 w/kg), 353 Normalized Power, 1082 calories, 81 TSS vs last hour: 246 average watts (3.5 w/kg), 306 Normalized Power, 889 calories, 61 TSS.

After 16 stages, Henderson is still showing explosive speed and power. Henderson’s 5-second peak power was a staggering 1054 watts (15.1 w/kg) – AND he hit this about 3.5 hours into the stage.

How good to you have to be to race in the Tour? 338 watts or 5.5 w/kg for nearly an hour puts a rider in the top 20%, 34th in the TT.

From the file we can see Sicard’s TT warm-up: 10 minute slow ramp up, 3.5 minutes at 285 watts, 3 minutes at 330 watts, and 3 minutes at 374 watts. 2 minute rests in between intervals.

Consistent pacing on the two climbs: The first climb (Cote de Puy Sanieres) was a little over 7 minutes shorter than the second climb so Sicard’s power output was bit higher on the first climb averaging 373 watts (6.1 w/kg) while spinning at an average of 84 rpms for about 16 minutes. His Normalized Power for the effort was 375 watts, very close to his average watts indicating a very smooth, steady effort. On the second climb, the Cote de Reallon, he averaged 363 watts (6 w/kg) at the same average cadence and crested the summit in about 23 minutes. His NP on the second climb was 375, again a very consistent effort.

Stage 18 – Gap to Alpe-d’Huez – 172.5 km

David Lopez (Team Sky) – 70th – 5:16:42

Defending Yellow: Lopez sets the pace the first time up Alpe d’Huez. Lopez averaged 360 watts (5.3 w/kg) for 45 minutes protecting team and race leader Chris Froome. This was where he set his 30- and 60-minute peak power outputs for the stage: 367 watts (5.4 w/kg) and 334 watts (4.9 w/kg), respectively.

The Queen stage of the Tour and the first time ever in 100 years that riders climb Alpe d’Huez twice in one stage! Lopez spent his energy on the first ascent, giving everything he could to keep Froome safe. The second time up, having already done his job for Froome and pulled off, Lopez clocked the climb at over 55 minutes (about 10 minutes longer) and he averaged 288 watts (4.2 w/kg).

HUGE effort for the day – 5093 Calories in 5 and half hours!

Stage 19 – Bourg-d’Oisans to Le Grand-Bornand – 204.5 km

David Lopez (Team Sky) – 62nd – 6:22:51

Two iconic climbs on Stage 19, Col du Glandon and Col de la Madeleine. It took Lopez just over an hour to summit the 21.6km, 4.8% grade Col du Glandon while putting out an average of 305 watts (4.5 w/kg). He turned it up a little on the steeper 19.2km, 7.9% grade Col de la Madeleine, averaging 325 watts (4.8 w/kg) in about the same time.

Steady pacing by a loyal lieutenant and the number 1. 1 watt was the difference between Lopez’s 30-minute (327 watts) and 60 minute (326 watts) peak powers for the stage, both set on the Col de la Madeleine. His Variability Index for these two time periods and the entire climb was 1.02 showing an extremely steady pace, protecting and guiding team leader Froome over the first two big climbs.

Up, up, up: 4562 meters (14967 feet) of climbing on Stage 19 in 204.5 km (127.1 miles). Nearly 15,000 feet of climbing after 3 weeks of racing is a great example of why the Tour is often considered the toughest race in the world.
