Chapo pinged recently and looks to be about 10 miles ahead of Cafro.
I didn't find actual start times, but I'm estimating that Fresh started roughly 30 minutes behind Jagged X, and Fresh is over an hour behind.
Seems like the gap between 1&2 has been getting a bit wider the past couple of hours. I'd say it's up from 30 miles to near 50. Will have to wait until Jagged pings again.
Maybe not, looks to still be about 30 miles...
