Having spent the winter and the early part of this year building upon my aerobic base, much of this part of the training cycle for La Marmotte is aimed to help build upon my Functional Threshold Power (FTP) - in short, the bigger the number... the better.
To this end I'm spending a fair bit of training time within the Sub Threshold or the "Sweet Spot" aspect of my power profile. This equates to roughly 88 - 94% of my FTP and is essentially on the verge of the top end tempo and bottom end lactate threshold levels.
While the hours spent at this level are not going to improve my VO2 Max or Anaerobic Capacity, it should help stimulate the bodily adaptations and improvements needed to spend the best part of half a day going over four mightily large mountains come the early part of July.
The graph below taken from my WKO+ shows one of these types of sessions, a classic 3 x 20 min interval ride on the turbo with 10 mins easy spin between each set.

For each interval I had planned to stay within a steady wattage range of 278 - 294 - I wasn't bothered about speed, heart rate or cadence. So, how did the session go?
Interval 1) - Ave Watts: 284
Interval 2) - Ave Watts: 287
Interval 3) - Ave Watts: 286
Perhaps naturally I was really pleased with this workout. Each of the intervals were well within the limits I'd set for myself and I finished each set feeling strong and fresh.
Hopefully a few more of these over the next few weeks will help me "fly" come July 7th.
