Switching from HR to Power mid plan

Just added a Power meter to my cx bike but I completed my 20 min field test with HR zones (about 2 weeks ago). Do I need to repeat the 20 min field test to dial in Power based zones? Currently in week 3 of the 6 weeks till Cyclocross plan.

Hi @pauly2ponds - I wouldn’t worry about it and just keep training by HR and record your power. You don’t want to interrupt your training plan with a field test and you can test at some point in the future. Also most of your cx intervals are full gas anyway!
