Hello, I am almost every day above the target strain. I do a lot of endurance sports. When I go running for 1.5 hours, I have often already reached 90%. But I would also like to go cycling or running for 2-3 hours. However, my target strain has never been higher than 80%, even with a recovery of 97%. How high would the recovery actually have to be in order for 80-100% strain to be recommended.
