After I used several "training load based" tools, I tried about 9 month ago a "regeneration based" system… and stuck it. For me it works great.



Hi Joe,

Lately I have moved from planning by workouts, more on TSS volume as opposed to hours or distance, while still following your guidelines around Base/Build/etc and specificity as "A" races get closer.

This question might be a bit pre-mature, as you haven't posted part 2 here yet (read it on TP).

I'm a bit confused on how one can increase their CTL by say 5 per week (which by my calculations means an average TSS/d of at least 50% greater than the current CTL) and yet still adhere anywhere close to the TSS guidelines you mentioned in part 2, while actually getting enough rest days in.

Considering that the moderate and easy days cancel each other out, that leaves a few hard days to try to increase the weekly average TSS. Furthermore, it seems that these workouts would have to be much > than 100% of CTL, which of course would result in a very high fatigue level. So I'm sure how many of those days (with quality) could be done in a week.

I agree with the above comment, that CTL among all the other metrics used are the best attempts at statistical measures in a training and racing program today. This would have worked great 35 years ago, when cycling was the main priority in my life. Today, I find though that the many external factors, being work, family, stress, travel, sleep, etc., has so much additional impact, that it voids the validity of the training statistics. For example, I can race and train really hard for three weeks and feel strong and recovered one month and another it may take me more than a week to recover from a hard race due to external factors. In short, my power output, heart rate and perceived effort remains the best gauge, of when to step on the gas, and when to rest.

insanebrian--Glad to hear you are basing training on TSS. Wise move. Here's an example of a 4.3 ramp rate from a recent week of mine starting with a CTL of 81.6: M-38 TSS, T-162, W-61, T-152, F-38, S-93, S-164. Total weekly TSS-708. I would call that hard-3, mod-2, easy-2. It certainly has a lot to do with one's capacity for hard workouts relative to aerobic vs anaerobic sessions and how they are scheduled.
