I can use yesterday as an example of how easy commute racks up TSS. I commuted 11miles each way, on the fixie and going home involves 3 tougher climbs, well tough on a fixie but in reality only 3 to 5 minutes each. 44TSS for 46minutes in and 55 TSS for 59minutes home. The last Sufferfest 4DP i did gave 84TSS in an hour. I also did a fairly easy 5.75k run, 35min 80TSS! (run with power so real TSS) a 30min TM run was only 55TSS (also with power and quite easy). I do think power on the run is a bit lower on the TM when looking at my history which makes sense.
