OUT OF SHAPE

I have to admit I am not in shape for my upcoming triathlon. I swam yesterday and felt pretty good, but when I woke up and went for a run, BLAH! My poor legs are not used to running outside anymore. Considering the triathlon is only a month away, I'm toast. Oh well, I wasn't really hoping to do great in it, but I really didn't want to do worse than I did last year. I guess I should have been better about training. Any good suggestions for quick training? It's just a short triathlon so I don't really need a lot of endurance, just enough to drag my carcass over the line in a respectable time. Tonight I'm riding 20 miles on the bike. We'll see how that goes. Luckily for me, my husband agreed to come with me, so if worse comes to worst (is that even how that saying goes?) I'll just draft off of him the whole time. We'll see how I feel tomorrow...
