Sporadic training

I've been having a hard time keeping up with the training on a frequent enough basis. I did those 2 runs in a row, then a week later, I did an 11 mile bike ride (in 55min - ugh!), and then today I ran 4 miles. I really had to push to get in all 4 miles and it took me 50 minutes, but I did it. I wanted to prove to myself that I could keep running even when I'm really tired. (It was hot, too.) I did more walking than I would have liked, but I did run (at my slow and steady pace) for most of it. Sometime in the next week I want to do a swim/bike/run combo and use the parking lot at the gym(pool) as my transition area. I've got a route planned from there with an 11 mile bike and 3 mile run. Wish me luck. (The race is in 2 weeks.)
