Power vs HR on the bike

    I’m following the IM70.3 tintermediate plan with power for bike and HR for run.

    After a hard interval workout e.g. CAn4, and I go into zone 2 power (215 watts), my HR will exceed zone 2 and stick in zone X.

    Question: Do I stick with the power and let my HR drift upwards or reduce power to keep my HR down. I’m figuring it’s stick with power, but I am prone to over doing it, so wanted to check!

    Hi Gareth,

    Go by power in these situations.
