Bouldering grade to mile time conversion

I think this is pretty good but they don't exactly match up at lower levels. For example, pull a somewhat active 25 year old off the street who has never seriously run or climbed before and I think running a sub-6:45 is much much more likely than them being able to climb a v5

Seems like a decent chart to me, the only thing that might be a little off is that I think there are a bunch more runners than climbers currently, and climbing as a popular sport is a lot newer. Therefore, running's talent pool is considerably larger, which skews the comparison between 3:45 and v17 a little. Also, a climber first conquered a v17 in 2016 vs Morceli running 3:44 in 1993, meaning there's been nearly one v17 climb per year since the first one and over 7 years per sub-3:45.

It's still probably a pretty good comparison, but I do think I'd call the sub-3:45 mile a little more impressive.

I also think the bins of 15 seconds for v10-11 shrinking to 6 seconds for v12 is a little abrupt. But overall this is a fun idea.

Yeah, the tricky part about the comparison at low levels is how much more technique-dependent climbing is compared to running. Someone who has never seriously trained for running still knows how to run to a much greater extent than someone who has never climbed knows how to climb.
