I am currently eyeing a JMT SOBO in Aug/Sept 2017 with my two oldest sons, who will be 12 and 13 at the time. I have quite a bit of backpacking experience, but this would be by far our most ambitious trip. We backpack together 4-6 times/yr, and they have been on trips lasting up to a week with 6-7 miles/day of fairly difficult terrain, with our most recent being the Teton Crest Trail last Sept. The will be 12 year old is an overachiever who loves to hike, and is totally excited about the opportunity. He’s done a couple of day hikes in the 15-20 mile range, and so I’m not concerned about his ability to complete the trip in the least. The 13 year old thinks he wants to go, but is really more into the fishing and the camping, than the hiking. Physically, I’m sure he’s capable of it, but I worry a bit about the attitude/mental aspect with him.
I have a couple of more intense trips planned for this summer and next of 4-5 days, covering 40+ miles in the Trinity Alps, with similar elevation gain to what we will experience on the JMT, just to make sure that they can hack it, and that they want to hack it. As much as I would love to take this trip with both of them, if I’m dealing with a whiny 13 year old after only a couple of 10 mile days, I’m going to ask him to reconsider whether he really wants to go on the trip.
My plan is to take a month off for the trip, trying to start around mid August (assuming I can get a permit), try to average 10 miles per day, and take a rest day once a week or so just to recover, relax, and do some extra fishing. I’ll probably take advantage of every reasonable resupply along the way just to keep the packs light, and will have my wife and father hiking in at Onion Valley to be our last resupply, and finish out the trip with us.
I am looking for any additional advice for those who have completed the JMT, especially with teenagers. Unfortunately, I don’t have the time off to take any longer through-hikes between now and then, probably just a couple of 4-5 day trips, but would welcome any advice/tips from those with far more through-hiking experience than myself.
