Pier to Peak altitudes

The day after the race I biked the course with my trusty altimeter (I don’t trust GPS altitudes). It took longer to bike up than it did to run — of course I did stop every mile to take a measurement so it’s not a fair comparison.

Location altitude increase grade

Camino Cielo 1015m 3330ft
Mile 11 1040m 3410ft 135m 440ft 8.3%
Gibraltar Rd (dirt
continuation into
Santa Ynes valley)
990m 3250ft
Mile 12 1022m 3350ft -18m -60ft -1.1%
park driveway 1150m 3770ft
Finish (13.1) 1170m 3840ft 148m
440ft 8.3%

Hmm. My measurement at the top is off by more than 100ft. Perhaps I should have used GPS.

I wanted to know what miles were steepest 4-5, 9-10, 10-11, 12-13.1 (The grades are the average over the entire mile (or 1.1 mile for the last))
