Training for running and swim events, how to balance?

Hi all! First post here. I swam on a team when I was really young (4-12) and just started again at 26. I have been running for a couple of years and run half marathons. I have one coming up in May, but also a swim competition in June. I have a swim coach and have started lessons with her, and plan on swimming 3x a week about 3000 yards each. I am not sure where to put weights in; because of running, I need to work my legs 2x a week, and usually do upper body weights 2x as well. Right now I'm thinking: Mon - 3000 yard swim Tues - short easy run (3 miles) leg work Wed- 3000 yard swim Thur - Interval run (4-5 miles) leg work Fri- swim/wupper body Sat- Long run (11 +) Sun- yoga/pilates I appreciate any advice. BTW, I will be competing in the 100 IM, 50 and 100 ***, and 200 free. I tried a Masters team session, but the one near me was too hard 4500-5000 yards in an hour and 15 minutes?? I would also love anything that will help me speedwise. I am more of an endurance athlete; I can run and swim forever, but hate (and suck at) swimming fast! Jen
