Realized there was no way I would make it to MAZAMA in time with the climbs still ahead, so cut it short and got to an amazing campsite in Newhalem. Ranger (also a cyclist) told me it was free for cyclists, and there is no camping fee.
Great thing about this stretch is that most of it was on a trail, which flattened it out a bit, and had very little traffic (bikes or people) on it.
Stunning Andre - you are already having adventures - awesome
