what are you specifically looking for? I have probably 30-40 from the last 9 months or soJohnny K said:Anyone got any MTB power meter files from a Powertap or SRM or whatever they can share on here?
I have seen plenty of road bike files but not as many from mountain bike rides. Thanks.
I would like to see a normal XC race and a hard group ride. See how they compare.fsrftc said:what are you specifically looking for? I have probably 30-40 from the last 9 months or so
hah, well I'm a bigger guy so its all relative?Poncharelli said:I would like to see a normal XC race and a hard group ride. See how they compare.
And with that, time in Zones. (aerobic, tempo, threshold, AC, etc. if possible).
Also, TSS, and IF. That way it gets normalized to your power level. (Which is a lot higher than the rest of us )

How did you label all those intervals? (road, byway, track, etc.). Did you just start an new interval real time, and rename later?
wetpaint said:For those that have road and mtb power, do you find a 100TSS road ride feels like a 100TSS MTB ride?
No TSS seems to be always much lower on a MTB ride for a given effort.
When mountain biking you do a lot of work is done that that power meter doesn't count.
A good example is on a pump track, I can have my heart rate at threshold without ever turning the pedals.
How does that power output compare to your road data and FTP figures? Was it constantly up and down or a climb followed by a descent?wetpaint said:Here's a lap from a smooth flowing single track

The constant breaks and interruptions in my rides don't affect the average power directly. The issue is that when you're only doing a few minutes between stops there isn't much incentive to try that hard so I end up taking it easy all the time instead. It's a bad habit on my part. In that ride on Tuesday for example I counted 24 stops.:madman: That included riding around someone's garden trying to work out where the restricted byway sign was pointing to, lots of gates and a few junctions in woods where I wasn't sure which turning to take.wetpaint said:Average power doesn't include stopped time, just coasting time, so the time you spend stopped won't affect your average, only the time coasting to a stop. There were some small rollers in that course, but it is fairly flat. The entire ride ended up having an IF of ~.7, it felt similar to what a .7 road ride would feel like, except the graph showed alot of spikes in power and coasting. On my typical road files, there is virtually no coasting and the power is quite constant.
