Missed training plan elev gain by 100 ft. Late start ran out of daylight and park closure time. Plan called for 15 miles/4,300 ft elev gain*. Felt weak last few miles of 2nd loop...possibly from cycling training on Sat. *During run I thought I needed 4,500 ft elev gain instead of 4,300 ft. Laps 1-3 Northern Peaks Tr. to Mountain Loop (reverse) to White Rocks back to Red Trail, includes hill repeat on White Tr. from White/Yellow connection Lap 4 Red to Orange Trail climb to Sugarloaf Mtn summit Lap 5 decent from Sugarloaf Summit on Orange Trail Lap 7-9 Northern Peaks Tr. to Mountain Loop (reverse) to White Rocks then back (via Blue to White Tr.), included hill repeats on Blue Trail (from Mt Ephraim Rd) and White Trail (from Yellow/White connection) Lap 8 White Trail climb from Sugarloaf Mtn Rd trail summit
