Map link didn't work for me.
16 miles for Day 2, mostly downhill with a hot springs at the end of the day, not too bad. Day 1 looks harder with 4,500' climb, full food load, and camping at high elevation (11,000') without time to acclimate. I'd go further and camp lower the first day, maybe save Sawtooth peak for another trip, but that's just me.
