Am I Going to Tri?

So, in an effort to think outside the running shoe and thanks to some good natured badgering by my friends I decided to set my sights on a triathlon in August.  This particular one happens to be only a few minutes from my house and falls on my birthday weekend.  What a great "come back" from injury, right?

Well, I started researching sprint tri training plans and this is what I found:


Does anyone see anything wrong with this plan?  Let me help you out.

The plan is 14 weeks long and the tri is 14 weeks away.  This should be great except for a couple things.  According to the plan, I'm supposed to run for 15 minutes today and I haven't been cleared to walk yet, much less run (and certainly not for a mile and a half).  What the eff am I supposed to do here?  Do I just do the bike, swim, and strength workouts until I can add in the running?  Do I scrap the whole idea?  Do I walk on the run days (assuming I'm cleared to walk at my doctor's appointment tomorrow)? HELP!

My other issue is pacing.  If I end up in the last swimming heat, there's a slight chance I won't make it out of the water by the 8:40 cutoff time (the swim here is 500 and yesterday I swam 800 in 24 minutes).  I probably will make the cutoff, but it's a slight concern.  My bigger concern is in the bike pacing.  Bikes need to be off the course within 1.5 hours from the 8:40 swim cutoff time.  If I make it out at the end of the swim, I'd have to haul ass on the bike to do 15 miles in 1.5 hours.  For folks with a fancy-ass tri bike or even a road bike, this isn't a problem.  My top speed on my hybrid "comfort" bike is about 12 mph and I can only imagine how much slower I'll be after the swim.  If by some miracle I make it through the bike portion without getting pulled off the course or penalized severely for all the various infractions in the rules I don't even understand (WTF is drafting? there are rules for passing?) I'll have 45 minutes to finish the 5k.  This normally wouldn't be an issue at all, but I'm not even sure I'll be able to run 3 miles by then.  I can't walk a 5k in 45 minutes.  Am I just over thinking this?  I'm a bit worried about spending $70 if I have no chance of finishing this thing (and there is no way I'm registering until the last possible moment).

I need some serious guidance people, so if you've been lurking around here and haven't commented, now is your chance.  Help a broken runner branch out into triathlons. M'kay?
