I haven't been using my power cranks for the last couple months since race season began. My lab testing though indicated a huge improvement in VO2 max from April to June test. VO2 increased from 58 to 67. Last nite I started my TT specific training for the Nova Scotia Provincials on Aug 22. I am using the power cranks in each session and a Chris Carmichael TT program from his first training book.
Wk 1 - 2x5km w/10min recovery between efforts
Wk 2 - 2x7.5km w/10 min recovery
Wk 3 - 2x10km w/10 min recovery
Wk 4 - 2x10km w/5 min recovery
Wk 5 - 2x15km w/5 min recovery
Wk 6 - 2x20km w/5 min recovery
Wk 7 - Tue - 1x7.5 / Sun - Prov ITT
I will be substituting my final lab test for the Wk 7 Training session.
The first session went excellent. As I mentioned I haven't been using the cranks for about 10 weeks I guess but they felt really great. I shortened the length to 167.5 after reading some of the latest info on the PC website. I am currently 176lbs, using a Cervelo P4 with Easton Aero wheels equipped with a SLC+ Powertap unit. I was given a 3hr bike fit with the purchase and am not set-up in a overly aggressive position as my hams are tight and need some flexibility training.
First session data
Conditions: 22 degrees / overcast / no wind / 6:15 p.m. start / A-B rolling course - Bishopville
5km #1 - Avg Speed - 41.8km/hr / Avg Watts - 343 / Time: 7:08
5km #2 - Avg Speed - 40.8km/hr / Avg Watts - 334 / Time: 7:23 (a bit more uphill on return)
I would have easily broken 7:00 min on the first attempt but couldn't get into my 11 cog. I think its a limit screw issue.
I will continue to update twice a week for the duration of the program, shorten the cranks next Tue as well for the same course, and finish up with posting my final lab results on Aug 17th.
I am using the 40k Prov ITT course for my Fri session. By Wk 6 I will be completing the entire out and back with a 5 min recovery in between 20km efforts.
