My 12 year old nephew is going on a 3-week bike tour this summer, from Boston into Maine. He's been training, using a trainer through the winter and now outdoors a couple of times. I did a 15 mile ride with him last weekend. I'm doing work on his bike to get it ready - will be replacing tires, freewheel, chain, brake pads, cables. He's going to have a blast. So much fun helping him get ready.
