Check out today's workout

So I had running club this morning, but as usual there was no turnout. I'm all ears if anybody has any suggestions on how to get people to come out and exercise! Anyway, I left the park and went to the rec center (I know that sounds weird, but it was a hilly park and you have NO idea how hard it is to push both kids in the jogging stroller up and down those hills). So at the rec center I started on the treadmill, but after 20 minutes I decided I wasn't feeling the treadmill vibe today so I abandoned ship and went to the bike. I was just going to ride for 30 minutes, but after 5 I had really had enough of that so I started working on plan C. So I rode the bike for 20 minutes and then went back to the treadmill and ran the fastest mile I could stand. Turns out after running for 20 minutes, biking for 20 minutes and then trying to force out a fast mile is harder than it seemed in my mind. But I managed 7 minutes 20 seconds. The whole time I was running I kept thinking that I need to do more of this type of training to better prepare for my 4 remaining triathlons. So I think I'll do just that, mix and match workouts...at least a few times a week. They are good for my body, my muscles need to know how to work when fatigued. And the better I can prepare for that fatigue the better I think I'll do in the races! Hope that is sound logic!
