Ramp Rate Calculation

I think the TSS ramp is more related to your current TSS level. For example, my last 8 weeks of training looks like this:

Week No TSS CTL CTL Ramp ATL ACWR
2020_38 420 14 10 59 4.2
2020_39 313 21 7 46 2.1
2020_40 390 31 9 54 1.8
2020_41 565 44 13 83 1.9
2020_42 636 55 11 96 1.7
2020_43 700 72 17 94 1.3
2020_44 772 81 8 117 1.4
2020_45 682 89 9 91 1.0
2020_46 744 98 9 111 1.1
2020_47 651 100 2 87 0.9
2020_48 752 102 3 107 1.1

According to this page:

A reasonable ramp rate is one that you maintain for a few weeks before taking a break for a few days. While it depends to a great extent on who the athlete is, I’ve found that an increase in CTL of about 5 to 8 points per week is about right for most.

I had the summer off due to some home improvements projects so although it looks like I was ramping substantially in weeks 41 - 43 (and I probably was to some degree), I had built up a base fitness during spring and early summer so was able to cope with this.

Here I am calculating my last 6 weeks exponentially weighted average Chronic Training Load (CTL) and then calculating a weekly CTL Ramp by comparing the current week CTL to the previous week CTL.

Additionally I calculate the last 7 days exponentially weighted average Acute Training Load (ATL) and calculate the Acute:Chronic Workload Ratio (ACWR) by dividing the ATL by the CTL.

This page gives more information all of these terms, but in order to think about TSS per ride I cite this text:

CTL and TSS are related and you can use the scale below to determine the intensity of a workout with respect to your current fitness. In this example, we’ll assume the athlete has a CTL of 50.
Hard Workout – A hard workout will result in a TSS score that is 50%-100% above your current CTL (TSS for a hard workout would be 75 – 100 TSS.)
Moderate Workout – A moderate workout will result in a TSS score that is 25% above your current CTL (TSS for a moderate workout would be 60-70 TSS.)
Easy Workout – An easy workout will result in a TSS score that is 10-25% below your current CTL (TSS for an easy workout would be 35-40 TSS)

As my CTL sits around 100 at present, I imagine that I should double those numbers so a Hard Workout would be 50% - 100% above 100, i.e. 150 - 200 TSS. A Moderate Workout should be 25% above my CTL, i.e. 125 TSS. An Easy Workout should be 10-25% below my CTL, i.e. 75-90 TSS.

I also found some interesting information about the ACWR from this page:

According to research by Dr. Tim Gabbett, the ‘sweets spot’ ratio when the risk of injury is reduced is 0.8-1.3
<1 – Athlete in a well-prepared state
0.8-1.3 – Training ‘sweet spot’ where injury risk is reduced
1.5 – Danger zone. More at risk of injury
1.8 – Danger zone 2. Further increased risk of injury

For my purposes, I have plotted this on a chart so that I am able to understand exactly what my progress is and to ensure I am training at the level that I want to be:

@Gato_Felix: Does this make sense?
