Something funky with your personal beats. It says your best 5k was in 35:35 but your best 10k was in 43:26. Not possible for those both to be true . I guess the 5k data is screwy since that is quite a slow 5k time.
Edit: seems maybe tht 5k is mislabeled, should be 5 miles... But that feels like a less standardized time.
Just a labeling issue. If you click on the 5k you get a detail popup on the right that says 5 miles, which is much more in line with several of the other times.
5 miles is not that uncommon a race distance in the US; 8k is very close, but you can still find both. (There are much fewer 3-mile or 6-mile races, those are mostly all 5ks and 10ks.) Though it's unclear if it was an organized race.
edit: it probably wasn't an organized race, there's a separate "races" tab.
Definitely a bug, will fix tomorrow, thanks for catching!
The label seems to be off. It’s 5 miles, not 5 kilometers. Based on the data below it and map.
