Aside from that, maybe hiking or cooking? Cooking is fun, I'd love it if it became designated quality time instead of seen as a chore. I don't know how anyone could hate cooking, unless they're somehow doing it wrong. He'd probably be bored with hiking though; I'm sure he gets enough of it when training, and he strikes me as more likely to be a trailrunner just due to added challenge... so walking would be boring by comparison.
