This is a very hard route and a GPS is highly recommended. There are a few off shoot trails that could lead you to lost places in the woods and some trails are not well marked.

This is it, the real deal, the full Lemmon Drop. Its a 35mile punch in the face that will leave you smiling. It will require all the skills you have acquired on and off the bike to complete. Its one of the chunkiest hardest rides in the United States and your only relief from the chunk is a small climb up a linking jeep road at 7000ft after that its back on again. This trail starts at the very top of Mt Lemmon and finishes at the very bottom its roughly 10000ft of descending. You will ride thru multiple climate zones so choose the time of year you do it wisely. Temps in the summer at the bottom are 100+ degrees and the top is closed for a portion of winter. I would say Oct/Nov & March/April are ideal. Usually we do a supply drop somewhere around the Bug Spring/Prison Camp area. Generally a group ride takes 8+hrs but fast guys can wrap a run up in 4.5hrs.
