Stage 14 – Limoux to Foix 191km

Chris Anker Sørensen (Team Saxo Tinkoff)

See Chris’ full power file here. 

301 TSS / 211 Average Power / 276 Normalized Power / 3898kj

  • Chris spent 55% of his time at under 88% of his FTP, 20% at 90 to 105% of his FTP and 26% of his time at 110 to 170% of this FTP. With that much time well below his FTP it looks as though he was trying to take an easier day to prepare for another attempt at a stage win later in the week.
  • 20 minute peak power of 385 watts was set on the final climb of the day.


Stage 15 – Samatan to Pau 158.5km

Berhnard Eisel (Team Sky)

See Bernhard’s full power file here. 

302 TSS / 300 Average Power / 363 Normalized Power /  4288kj

  • The first 1.5 hours were aggressive and Team Sky had to pull back any threats to the overall lead of Bradley Wiggins. This section cost Eisel 147 TSS, indicating it what an all out effort for the entire 1.5 hours.
  • The final 90 minutes of the stage were quite different with the last 1.5 hours having 86.4 TSS and 278 Average watts.
  • Since we’ve been following Eisel he has accumulated over 3720 TSS points in 2 weeks. By comparison, a recreational cyclist might accumulate 250 TSS points per week riding about 6 hours at an easy to moderate pace.


Stage 16 – Pau to Bagnéres-de-Luchon 197km

Chris Anker Sørensen (Team Saxo Tinkoff)

See Chris’ full power file here. 

420 TSS / 274 Average Power / 312 Normalized Power / 5533kj

  • Second on the stage! Only 25km into the stage Sørensen made what would end up being the winning break. He sepnt about 170km off the front and raced to 2nd place finish.
  • Today’s stage was the hardest of the Tour so far. It comprised of the infamous “circle of death” of the Col d’Aubisque, Col du Tourmalet, Col d’Aspin and Col de Pyresourde. The Col du Tourmalet is the highest point of the Tour.
  • 420.1 TSS is the highest TSS score we’ve seen of any rider so far.
  • Looking at the final descent, Sørensen is chasing down Voeckler with all he has. He actually set his peak 12 minute heart rate while going downhill!


Stage 17 – Bagnéres-de-Luchon to Peyragudes 143.5km

Janez Brajkovic (Team Astana)

See Janez’s full power file here. 

317 TSS / 255 Average Power / 308 Normalized Power / 3984kj

  • During the last mountain top finish and last mountain stage, Brajkovic holds on to his goal of a top 10 finish!
  • 30 minute peak power for the Tour so far is set after 20 days of racing. He held 375 average watts.


Stage 18 – Blagnac to Brive-la-Gillarde 222.5km

Bernhard Eisel (Team Sky)

See Bernhard’s full power file here. 

355 TSS / 286 Average Power / 435 Normalized Power / 5201kj

  • A high-stakes stage characterized by several riders attacking aggressively early on. Eisel’s teammate Mark Cavendis wins the stage with a lead out from the Yellow jersey himself, teammate Bradley Wiggins.
  • Fast but not truly flat: Considered a flat stage, it stil had several short punchy climbs yet Eisel averaged 43.4 km/h.
  • 355.1 TSS is one of the highest TSS scores for Eisel so far.


Stage 19 – Bonneval to Chartres 53.5km

Chris Anker Sørensen (Team Saxo Tinkoff)

See Chris’ full power file here. 

117 TSS / 357 Average Power / 45.4 km/h Average Speed / 5.6 w/kg

  • Let’s compare the 1st ITT to this final one. Stage 9 – 41.5 km/h, 330W, 342NP vs. Stage 19 – 53.5 km/h, 357W.
  • Consistency is the key to a strong ITT. Sørensen’s 1.01 VI indicates a very smooth power output. Despite changes in elevation his cadence and output remain consistent. He is obviously a very experienced TT rider.
