How do I fix a GPS track with massive location / GPS outliers and straight-line jumps? [Solved]
Posted: Sat Aug 29, 2026 6:54 pm
I have been trolling through my data files and have several older FIT files that used a Wahoo Bolt or an old Edge computer. I see some errant GPS points/sections and I can't quite figure out a good way to remove them.
Could you have a look at the attached FIT file?
The problem seems to be that in one case I was stopped for a bit, and the GPS seemed to jump out to some other locations and back. It is far more than a single data point to delete. I am not sure if your Merge / Repair fit tool can do multiple point deletes easily. In another instance in the same file, it jumped to another place and came back to a different point. I am ok with losing the intervening data - I just don't want a final GPS track that has points I never rode on it, even if it means losing some travel that was never accurately recorded. I read the tutorials on single point deletion, and on segment reconstruction. I think I'm basically after segment deletion.
Any suggestions? As usual thanks for building and supporting these tools. Most helpful.
