Back in August I did a 5K race in a time of 31:05 which gave me a TP of 10:20 min/mile. I used those zones throughout the HM training program, which I recently completed. I did another 5K race yesterday in 29:22 (thanks 80/20) which gives a TP of 9:48 min/mile. Currently I am in the maintenance program and plan to start another HM plan after the 1st of the year. Should I update my pace zones now?
Thanks for the replies Gerald and David! I have updated my pace zones and will keep on with the maintenance plan. For the LTHR test, is there a rule of thumb for how long I should run at my TP to determine my LTHR?
