Is doing over the planned TSS an issue?

Quick question, I am following Low Volume Base plan, I did low volume to ensure I can complete all workouts. Over the last month, I have found the time to add in additional rides, particularly with a mate on a Sunday. The issue (if it is an issue) is that the Sunday ride is relatively hard and long… over a 100Km and a TSS of 400 - this obviously throws out the total TSS which is often double the plan. I query if this is an issue on a low volume plan ? my thoughts are that it will not impede program goals and will just add additional stress which is a good thing (as long as I take recover weeks).

As long as you can handle the stress its not an issue I regularly go over my TSS ever week except on recovery weeks. Personally I use to SSLV plan and then fill my days with long Z2 rides or if the weather is right Ill hit the road. usually. Usually im anywhere from 150-300 TSS over what is prescribed from TR on any week. But everyone is different and handles stress in different ways. 2 years ago 3 TR work outs was to much for me. Today I blow threw them recover and ask, may i have another. I find that every week I increase my stress in respect to the weeks work out… gradually increasing my TSS over what TR sets as the block goes on. then back off when recovery week comes. rinse and repeat.

If you are really getting over 400 TSS for a 100km ride, then either your power meter is reading high or your FTP is set way low, or both.

400 TSS for 100km is roughly averaging 100TSS/hr or more. 100TSS per hour equates to riding at threshold for an hour. So your TSS for the weekend ride equates to riding threshold or above for around 3 to 4 hours, which isn’t remotely possible.


Yeah, 400 tss is burley, something isnt right

Yeah, that’s intense for a 100Km ride, but he also didn’t say it took him 3hrs. I’m sure TSS was rounded up, and perhaps it took over 6hrs for a more manageable TSS? All I can say is when I go 4.5hrs @ ~.80-0.85IF, I’m completely wrecked. Astronomically so. And that would be <= 325TSS.

That’s my point: if the time stretches out, unless most of it is climbing, the intensity would go down, so the total TSS would be even lower.

TSS is proportional to IF^2. So as IF drops below 1, the TSS per unit of time drops even faster:

  • IF = 1.0, TSS = 100 / hr
  • IF = 0.9, TSS = 81 / hr
  • IF = 0.8, TSS = 64 / hr
  • IF = 0.7, TSS = 49 / hr

Gotcha! Makes sense.

Thanks, will check what I am doing. Appears something is not right.
