Yeah I’m with @chriswim there. Whilst I love tracking and monitoring progress etc on the various platforms, I don’t rely on them.
I’ve mentioned elsewhere that Training Peaks for example really overestimated tss compared to running (especially when hills and technical terrain are involved), and this really can skew the data. I can go for a 2 hour pootle on my bike and it’ll give me a higher tss than a 1 hour hard run on hilly terrain.
I also tracked my pure running mileage over both a 10 day period, a 7 day rolling and a normal 7 day period. Due to the way in which I could get my running (double days most days) sometimes I’d find that I’d covered 50km+ in about 29 hours if I didn’t take a slightly wider view of what was going on.
Sorry, don’t know much about the science of it all. But as another example of 1 I have a good mate who is a high volume, very talented athlete, and he works in air traffic control on 4 day shifts (I think). So he plans in 12 day blocks. Worked for him for years.
