    Good morning,

    So far loving the 80/20 70.3 plan. I am currently running with pace zones and bike with power zones. My question is this:

    On race day is there any strategy to what zones I should remain in during the race. I have done Olympic distance in past so going full throttle was not an issue but I feel at the 70.3 distance I will need to pace myself in a specific zone to get the most fuel economy out of myself. Thanks!


    As per 8020 book 70.3 should be in between 77-85%ftp bike, … But run is difficult to answer.

    I think you’ll find the perfect solution to this outlined in our document Race Pacing.

    High Zone 2 to Mid Zone X is ideal for both the bike and run in a 70.3. You’ll want to test these intensities in your race simulations bricks scheduled over the last ~6 weeks of your 70.3 plan.
