I’ve got an old skool wired powertap, and I’ve been using Strava on my phone to track rides. I don’t suppose anyone knows a way of adding the power data to the ride..?

you need a power meter…

Strava do try and work out power, if you have a cadence sensor, but I would guess it’s very unreliable

Most things about strava are unrelaible, like when I beat a mate up a climb by some margin, and his iPhone gives him a better time than my Android gives me.

It doesn’t matter, I won, but it’s annoying.

Most things about strava using a gps device with a poor sampling rate & accuracy are unrelaible

ftfy 😉

I think the trick is going to be to attach the relevant power readings to each gps sample that you have. Could get complicated.

if you have a file with time stamps from both the gps and the power meter i guess it is theorectically possible to create a single file. You would need to know what Strava needs the file to look like to work though. What are the correct line headers in the GPX/TCX you would have to create.

your android probably thought you were still climbing the hill due to a poor gps chip set.

my iphones pretty close to the forerunner 305.

me and my edge fell out the other week as it had me crossing a river twice during my ride- piece of craps in 3 bits now.

looking at replacements now.

Interesting question. You’d need to upload both files and then meege them. Not possible in Strava as I know so I’d look at TrainingPeaks or similar.

I updated the software in mine to be Ant+ but it was wireless to begin with.

Yes you’ll struggle to do that frankly. Probably a case of upgrading to wireless ANT+, then either getting an ANT+ dongle for your phone, or using a different head unit.

Does it really matter though? Unless you’re using Premium it adds nothing special, and presumably if you’ve had a PT long enough to still have a wired one you have some better software for analysis and what not.

😳 I read that as laptop…

I believe the only way to do it is with an ANT+ power meter.

You could probably use SportTracks to combine the files. Then export to a TCX file or similar, and upload to Strava.

Though it will depend on how well the files are synchronized. ie do they start at the same time, and is the time accurate.

I would expect there’d be enough discrepancies that it wouldn’t really help!

Oh ok then, where’s my fat bundle of cash sitting around doing nothing?

😉

Some kind of trickery might be required.. I may have to get coding.

I’ve got the usb type dongle if that’s any good to you?

Make a great geek project

USB dongle for which bit?

The actual hub, unscrew the plastic non drive side cover and there is an interface. The dongle was a once only operation but the geek in me says it should be hackable

Wait.. you mean a dongle to convert wired to wireless?!

😯

Yes, definitely interested!

What do you mean once only operation?

I believe it was for a firmware update, but you may be able to hack it to make it transmit wirelessly. That could be bollocks though.

I’ve considered a wireless hack. You can apparently get ANT+ transceivers, I reckon you could figure out how the wired data was transmitted. I’d start with an oscilloscope, see if it’s some kind of pulse-width setup. If I were designing something like that I would not go to the trouble of encoding it digitally at the hub end – keep all the electronics in the computer.

PM me your address and I’ll dig it out once I’m back home

Eat fewer cakes. 😉
