I have never paid attention to TSS, so I don’t know what is normal. Just glancing at my TR calendar it looks like I flat around 800. My biggest this year was 1200, which was a week where I did three races in a row at Sea Otter (road race, circuit race, and XC) and added extra miles after the races for fun. I ride 20-25 hours a week.
I don’t track stress from running, gym, or anything else. I just don’t care.
