Thanks to Dave Mackey for setting the standard in 2003! 13 years in Boulder is a good long run!
43:22 for North to South (oneway) and 1:28:52 roundtrip
Start at gate, down from Chautauqua ranger cottage, turned at South Boulder TH, where trail meets parking lot.
NOTE: Andy used the true Mesa Trail at the south end, not the shorter Mesa Connector.
