It's impossible to run like this! I have many other segments with people with pace better than Usain Bolt 😅!
I think you could add the option of report inconsistent records, or creat a simple checks, for examples, no human can run under 1:10 min/km! Maybe creat an algorithm to check pace and information like acelaration and gps. If the run has too many inconsistencies, like too many acceleration spikes, speed over the human capacity, jumped buildings, then they are not eligible for CRs.
