Thanks very much Ric! So much of the info is blocked from here that I cannot read some of the links. I do not have a watt meter, but I have noticed that my HR at a given level of work, ie percieved effort and speed, has decreased. I was able to ride harder yesterday at a lower level yet attain higher avg speed and shorter ride time than 2 months ago. Boy have I noted the harder to get to that level here lately. Very noticable after a full week of rest.
Thanks for the info!
John
