Here’s my ‘Fitness and Freshness’ chart from Strava
I don’t think it takes a genius to work out where the heart attack event was. Prior to that I was trundling along at a steady level of fitness at around the 110 mark. I don’t think this has unit associated with it as it’s a measure of fitness based on training load. It’s probably a derivative of the 7 day rolling TSS from a Performance Management Chart but I’m not 100% sure. Whatever it is it had been steady for a number of months at a decent level.
I then had a heart attack and was unable to do any training so you can see it drop off over a period of 2 months or so to the level it is at now (around 25) I have started a little bit of exercise ow though so if you look closely you can see that it has finally levelled off and even increased slightly last week. Something tells me it’s going to be a long hard slog to get it back up to a decent level and I don’t think it is likely to ever get back up above 100. Oh well, hopefully it’ll be fun trying to increase it at least a little bit.
And, in case you wanted confirmation of this loss of fitness, here’s a similar chart from intervals.icu. This has a slightly longer time period which shows that the level I was at prior to my heart attack was actually not that high anyway. A few months before that it was actually quite a bit higher. This one also shows fatigue levels, form and a bar chart ofweekly load too.
