Grossly overestimated load on multi-day race

[Tor_Hovland]

I did the Atlas Mountain Race over 7 days earlier this month. Strava gave it a relative effort of 1467, which seems about right. For comparison, the 3 day Paris-Brest-Paris was a relative effort of 808.

But Intervals gave PBP a load of 1665 while AMR got 73954!

The suspect activity is here: Intervals.icu

Some possible explanations:

• I had to reduce the GPS file to 4 seconds per data point, in order for Strava to allow uploading it.
• I had a few occurrences of elevated heart rate close to the halfway point, such as almost 2 minutes with a recorded HR of about 190.
• PBP was with a power meter. AMR was HR only.

I don’t know how Strava calculates relative effort. Intervals.icu tries to match all the load calculations to produce similar results to using power and TSS.

You have HR Training load set to “Time in HR Zones” which doesn’t seem to be doing well with this. I changed it to “HRSS” which depends on resting HR, LTHR and max HR:

I then returned to AMR and did Actions → Re-analyze. The new load is 2783 which seems more reasonable (but still bonkers!).

That is a crazy ride BTW! Almost 200km/day for 7 days straight on a MTB!

Thanks for the fix!

And yes, it’s a bonkers ride
