I am a weekend warrior, usually do a 80~150km ride on the weekends, and 2 or 3 indoor session during the weekdays with xert.
i found mpa and tte especially useful when to control my pace during short time efforts (mostly hill segments)
however im not sure what the best use to intuitively use mpa to manage long range efforts, to make it sustainable, but just sustainable so that im putting my best endurance effort.
obviously trying to remain on the sweet spot would be best, but many causes drift you away from the ss zone (traffic, small hills, etc)
my initial assumption is that if i try to maintain my mpa around 90% of baseline it would to just challanging enough, but not to tough. I havent had a chance.to validate my ideas yet.
anyone had experience/or better ways to use xert metrics to manage long efforts on lomg rides on the fly?
