Fastest pace leaderboard doesn’t work: Just remove it.
It’s far too subject to GPS error, or bike rides miscategorized. Case in point:
I don’t think these three guys (and I know Nate Swanberg personally. He’s fast, but not that fast!) just broke world records this month. (For the record, ~2:45 min/km for 21.1 is the world record half-marathon pace == 58 minutes)
Also: One thing you are missing is the absolute leaders in number of streets complete. But I know this is kinda lame because it won’t really change all that much, and is very location dependent. But I would love to see the maps of the worlds greatest heatmappers.
