Option 1

I think the idea of building something you if you absolutely have to plaster your name on something has the most charm. This way you can do some actual, tangible good instead of benefitting of a place or institution that was existed before you already and which was built an maintained by other people. What I would try to build up is a sports complex for everyone, with low entry barriers and the chance for people of all ages, shapes and fitness levels, to enjoy sports. It should have pitches and facilities for all kinds of team sports as well as individual workouts. None of them would be too fancy so that the facilities are easy to maintain and the goal would be to give as many people as possible the chance to participate in these activities. I would also add some common areas like a food court or just hang out areas or a pool, so that people can socialize and mingle after their workout as well. That's a facilitiy I'd love to lend my name to!
