Meface, I love tip 7, hahahaha.
As the others have said, get out on the bike, that's the most important thing, as your running is obviously fine. I guess the Wimbleball route is hilly (?), so make sure you train on the hills too. OW swimming should be starting up soon, so you'll be able to get a few sessions in too. I probably only did about 6 or 7 OW swims before my HIM, and that was fine.
Good luck, and we'll no doubt see you at an IM next year then....
