Hi @SimontheBike, great effort on this activity! Was this your own workout, or one you did elsewhere?
Now you might have a extraordinary capacity to suffer in agony, but whatâs more likely the case is that your current fitness signature in Xert is under-estimating your âtrueâ fitness signature. As @wescaine mentioned, I suspect that this activity doesnât accurately capture your true max. A difficulty score of 290 is INSANE! Dr. Stephen Cheung, our Chief Sports Scientist here at Xert is known for being able to sustain a pretty high difficulty score, but even he is often forced to back off around a 200 DS. In my own data, I know that hitting a DS of ~165 is about my maximum tolerable limit - Iâm simply unable to continue riding hard and am typically (mentally) forced to back down.
If you open this activity in Xert and go to âAdvanced MPAâ and bump up your Threshold Power by ~5W, I suspect youâd see a more accurate representation of the Difficulty Score, XSS, etc.
