There is already a process in place to flag new activities that are posted at an impossible speed, and to keep them from appearing on leaderboard and segment records.
The problem is, this has not been applied retroactively. So there are thousands of older records where someone has, accidentally or on purpose, posted an activity with an impossible speed.
For example, when I see a running activity with a segment that's over 1 mile long, and the speed is faster than a 3 minute mile. This is either a person who rode their bicycle, forgot and left their activity on while driving their car, or is intentionally using something else such as an e-bike to "game the system."
For those of us who work hard to gain a little bit more speed while running or biking, it can discouraging to see a bunch of older records with obviously incorrect and impossible speeds.
Please consider a retroactive filter to go back through and remove these impossible records from the leaderboards and segment records. Thanks!
