Cardio (trainer - legs) 55:21 [3]
ahr:133 max:168 shoes: Gekko
Another test of the trainer, this time with the heart monitor on so I could start to map power to heart rate. I did it by the book with a nice long warm up, ramping up the power every 5 minutes for 30 minutes before testing some limits. Today I did everything with slope set to 0
In the tighter part of the cassette each gear added about 15 watts.
Upping the cadence was less linear, but at moderate effort 10 rpm (from 80 baseline) added about 20 watts.
100-110 watts felt like a recreational ride - heart rate < 100
120-130 watts seems like a good early warmup/cool down - heart rate < 120
150 watts was good for recovery from a higher effort - heart rate drops from 160s to 120s
160-170 watts felt sustainable for quite a long time - I expect this will work out to be my steady state rate; i.e. one I could manage for 100km - heart rate low 140s
200-250 watts will need some testing to see how long I can hold it - another day for that - heart rate 150s
After a good warm up I knocked it into the top gear and eased into a progressive cadence increase.
512 watts on first run
second run, I couldn't hit 500, but I realized I had been so focused on the trainer numbers that I had neglected my breathing, so I took a recovery to get that in order
550 watts on the third run - I don't think I can beat this without increasing the slope. The cadence is about as high as I can go in my top gear. Another day, I'll see if I have enough power in my legs to beat that reading on a modest slope.
My heart rate peaked at 168 on each run, so there is certainly potential to hit a bigger number.
Other observations:
It will be a nuisance to overlay my Garmin chart with the Tacx chart to see how the heart rate moves with power. I got such a good deal on the trainer, I can't really complain. I may look for a USB ANT to use with the Garmin strap.
I'll have to break down and get a front wheel support to replace the phone book I've used for years. I'll set it to hold the wheel slightly right to give my left knee more clearance from the bar mounted controller.
The Bacchetta seat is not very comfortable in the seating position I had to set to clear the handle bar hardware - enough so that I stopped short of the planned hour.
