You may have noticed on Strava that there is quite an extensive list of Sports into which activities can be categorised. Here, for no reason other than curiosity, is a chart showing relatively how many of each activity we have on Crickles:
Since the number of activities in each Sport ranges from Rides, which is in six figures, down to Handcycles, for which we only have one, I’ve used a log scale.
Cardiac Stress Score can be calculated for any of these Sports in which a heart rate monitor is used (and estimated imprecisely even if one isn’t).
UPDATE: the algorithm for calculating CSS in the absence of heart rate data has been significantly enhanced since the time of writing.
