"everyone would think I was a nice person doing nice things for people in need" Notwithstanding effective altruists. That aside, when I spent more time doing running & triathlon there was an unspoken rule that people don't ask the group for charitable funding for these things. A large number of charity marathon runners will be effectively buying a place in a race they did not good-for-age qualify for. There's nothing wrong with that and cool that a proportion of the ticket price goes to charity, but it would be great if more people could just own it. The general rule is don't ask other people to pay for your fun adventure activities.
