Vertical 2 2.56.18 - Calculating Wrong Elevation Gain from GPX files + Climb Guidance Wrong during hike
-
Has anyone noticed that Vertical 2 recently has been giving the wrong elevation gain when uploading the GPX file and during the activity via Climb Guidance but post hike everything is perfect?
I haven’t noticed this prior to 2.56.18 update. It seems like a big thing to miss when I typically do over 800m most hikes, so i doubt it happened prior to the update.I had an update early July on my watch and 2 decent hikes i had uploaded to my watch with 1000m elevation gain for a trail which only has 800m elevation gain for 2 identical trail stats for 2 trails and even during the trail it showed in the climbing guidance tile that is was supposed to go 200m-400m higher than the trail was, then i looked at the elevation i was at and needed to get to and it showed the proper alitutde i was at and the top of the climb altitude. I had to tell my wife that i had to approximately 200m from the climbing guidance so i couldn’t give her an exact number when she asked how much climb is left
TDLR:
- Pre-hike: App/watch elevation gain is wrong via GPX file
- During the hike: climb guidance is wrong, current/peak elevation tile using altimetre/barometre is right
- Post-hike: all tracking is spot on even with strava gps corrections.Sadly i didn’t think about taking pictures during the hike because i wasn’t going to make a post about it but just decided i wanted to make a post about it.
Try this for yourselves if you have Alltrails pro/peak (these are the most popular trails in both areas and would have been vetted by Alltrails staff)
- https://www.alltrails.com/trail/peru/ancash/sendero-laguna-69 elevation gain is 830m but the suunto app says it’s 1049m
- https://www.alltrails.com/trail/us/washington/yellow-aster-butte-trail elevation gain is 861m and on the suunto app it says 1261m. (oddly enough it went to about 1000m on my watch)
By the way, i’ve used over 500 alltrails gpx files prior and never have seen this before. I know for a fact it’s not on Alltrail’s side. Plus minus 100m is fine but 200m+ is a little excessive when you clearly look at the map and it’s just an up and down trail with no dips.
Can you guys pay attention to this for your upcoming hikes when uploading GPX files?
- It doesn’t happen every time post update because https://www.alltrails.com/trail/peru/ancash/pico-mateo--2 was spot on pre-during-post.
