Hello! I’d love some guidance with my threshold pacing/zones.
I did a 30 minute TT to determine my threshold pace less than a month ago. It was on my treadmill with a 1% incline. According to my results, my threshold pace is 9:09 min/mile (my watch recorded a bit faster, but I’m going off what my treadmill said).
The resulting zones feel good when running my usual neighborhood routes on pavement, but I do spend about half my training trail running (definitely my preferred outlet, but I can’t always make the drive there). My pace zones on trails feel too strenuous. Especially when there’s a lot of undulating hills and tricky footing.
My question is, should I adjust my pace threshold in trainingpeaks to reflect the terrain (road vs. trail) before every run? In which case, I’d need to do a time trial on the trails? I’m not sure how the pace flip-flopping would work with my Garmin and whether it would update the paces efficiently.
Thank you for your help!
