What do you do with GPS data?

[Edwardoka]

A lot of people feel a bit uneasy about Strava, it took me a while to become a convert from Endomondo, before that I used Google MyTracks (wish I'd kept the data from that one), but once I actually tried it out, it became an interesting training partner rather than the reason for riding. I used to map my rides by hand using Photoshop, believe it or not.... until I rode a 200 mile tour and the image became impossibly vast and full of blank spaces.

Try Strava - you don't have to acknowledge segments if you don't want to.

Edit for clarification: you can add privacy zones that stop people seeing where you live and work, you can set your profile so that ride details are visible to authorised followers only, and you can use GPX tools to offset your ride times to mask when you're out on the bike as well.

Strava and spreadsheets for me. I've also saved copies of all my gpx files so if something better than Strava comes along I can fill somebodies server for them.

It would be quicker and easier if Nigel lists what he doesn't do with his gps data

Forget spreadsheets, our Nigel uses databases and some complex formulae that even the NASA boffins would be proud of.

If it doesn't use sin and sqrt I'm not interested

Dunno if other sites have this but ridewithgps has a "friends only" option so your rides aren't visible to every Tim Dick and Harry, just your friends.

I use this but I should also add that I don't actually have any friends!

You can add me if you want

Not even for spheroid distance calculations?

Hmm, this gives me an idea - calculating the size of areas that have been completely enclosed by rides. *ponders*

My data, which I am interested in is pretty liner. most of it (if not all) could be done without gps data, the gps is good for elevation, should my 705 not record correctly, as the Bryton R20 is a bit naff at this.

@Edwardoka not many sites will help yo explain why you are slower on one chainset set than another set up, I changed my front from 52/40/30 to 50/38/26 and my average speed dropped from 15.76mph to 15.33mph ok its a bit colder so factor that in, but what my data base show is that the rides (days) are actually a little more difficult.

Whilst I was on the 9sp set up the drop from 42th middle to 40th saw an increase.

That is some pretty good analysis! (your elevation-per-day seems to be higher on the 50-38-26 which would also be a factor?)

Elevation per day on its own can be misleading as on the 50/38/26 set up I am doing 5 miles a day more, the ft/mile gives a better idea, the difficulty takes into account elevation and distance.

The 8sp set up was more difficult per mile, but as the distance was much less per day it was actually quite easy.

i am running a garmin touring and strava and garmin connect
i just upload to review my ride and see where i have been (on anything more than about 10 miles i just lose track especially if it somewhere i haven't ridden before) and compare speed and distance etc to previous rides
also as in my signature here that i manually update is a ticker to keep track of roughly my miles this year

on strava only my mates can see my rides and they all know where i live anywhere, on GC i think only i can view it? oh course i haven't a clue what strava does with my data!

TBH i feel fairly safe with both entrance points to our house gaurded by big heavy 5 bar lever deadlock thingies and the building the bike is behind two big chubb locks
and a double skin of the largest concrete blocks we could get ouyr hands on and clad in weather boarding and then insulated which adds a bit extra to dig through, basically there are a lot easier bikes to steal worth a lot more!

behind 2 of these:

You can alter the privacy settings of the sites and I always start tracking rides and rides a bit away to make it harder to identify the house.
One of my neighbours has been complaining his shed keeps getting broken into though.

Whenever I put a route file up on t' web, I always start it from the same car park in Hebden Bridge which is where I recommend that people park if they are driving over with their bikes.

I stopped using strava this summer and deleted all my rides on there (3 years worth) when a couple of riders living very near me had only their road bikes stolen in what looked like targeted thefts. Even though I had the post code privacy option turned on it wasn't hard to predict where the general area where I live.
I now upload my rides to training peaks, I can also put the gym rowing sessions on there too. Its free and totally private.
Now I find I enjoy my rides out more because i am not trying to beat pb,s all the time or get into the top 100 on sections anymore.
Out on the road I still like to compete on the climbs with people of similar ability to myself but if i am out on my own i no longer try to smash it on every hill or only go out on certain routes because the wind is just right.
I am glad I got rid of strava.
