The climb is really easy. The hardest bit is there's a couple of steep staircases... but the bridge itself isn't hard. And they do stop a lot. I think if you're feeling well you should be ok. I guess the only thing is you're not allowed to take anything with you, so if you think you'll be hot & thirsty you might need to take that into consideration. You can't even take a tissue with you! They provide you with hankies! ick! lol.
