In this base period, if a race about 1 time per month, it will ruin my base?

Beto--I seriously doubt it.


Hi Joe, using your test my zone 2 is 143 - 150 but according to Maff my target should be 128. Your zones line up better with my past performance heart rates but the difference has me wondering. Any suggestions?
Thanks for the great information.

Pdxagogo--A formula based on average heart rate only works if you're average. Many (most?) aren''t.
