With the help of TrainingPeaks we take a closer look at the American's podium performance on stage 11.
Billed as one of the toughest Grand Tour stages in recent memory, stage 11 at the Vuelta a Espana was memorable for a number of reasons, including one of the best rides of Ian Boswell's career.
The young American forced his way into the day's breakaway and held on over a savage parcours to claim third overall on the stage.
With the help of TrainingPeaks we take a look at the data behind the performance, and what it took to excel on such a feared Grand Tour stage:
- Immediately, this stage started out hard. Starting just 5km in, Boswell set his Peak 1 Hour Power of 332 watts, or 4.88w/kg. while ascending the Category 1 Collada de la Beixalis and half of the Category 1 Coll d'Ordino. During this same strech, Boswell set all of his peak power values under one hour. This section is also where Boswell made it into the main break of the day.
- After a 25 minute descent, Boswell again put in a big effort. Climbing the Category 1 Coll de la Rabassa and the HC Collade de la Gallina, Boswell put out his Peak 90 Minute Power of 312 watts, or 4.58w/kg. and averaging 79 rpm.
- Having ridden for four hours at an average of 284 watts, Boswell came to the final climb of the day, the Category 1 Alto Els Cortals d'Encamp. For 40 minutes his Normalized Power® was 339 watts while averaging 20.3km/h.
- Boswell's Peak 1, 1:30, and 2 hour power values have very little overlapping sections. This is very rare and shows how hard the day was from start to finish.
- Over the full stage, Boswell climbed 4724m (15,971 feet) averaged 295 watts, 82rpm, 29.1km/h, and burned 4868 calories.
