Upwind vs Uphill
Last big run before the Disney Marathon:
21 miles at 8:58/mile pace.
Running Upwind is harder than running Uphill.
'Nuff said.
Too Many Questions
Over/unders were the order of the day last night. The Computrainer profile looked like a castle wall with three 10 min intervals of five 2 min efforts cycling from 95% to 105% of threshold watts. I thought it would be pretty wicked but it turned out not so bad. I never thought I'd consider the 95% level as a rest point but after riding at 105% it sure was a relief to drop back even that small amount.
During the ride, one thing I noticed, was that my HR did not hit the 105% level and topped out at the 102% level each time. However my cadence was about 85 rpm--10 RPMs slower than my usual 95 rpm interval pace. This got me wondering if there is a sweet spot of balance between the heart and legs and how do you find it? Had I been allowing my legs to coast during the previous interval sessions by spinning faster thus transferring all the work to my heart/lungs? Is there a point where you can spin out the heart--i.e. be riding at a threshold HR level while still not riding at true threshold watts? Is there a natural level that your body self selects regarding HR and adjusts the work the legs are doing to get it there and keep it there? I don't know.
Anybody have any thoughts?
