Started using Strava and wondered if anyone knew if the stats it collects via my iPhone are reliable? Went out for a 60k ride up 7 East Devon Hills yesterday, and the app said 1200m and then corrected itself to 1015m of climbing. Then I saw a ride 2 mates did together this morning - 1 said 400m and the other said 650m!
If the elevation is off, does that mean the top speeds are as well? I was quite proud of my 50mph segment from the top of Observatory Hill down to Sidbury!
