Near term addition of HIM to training program

Hi all,

I'm in the midst of training for an Olympic Distance tri. The past 4 summers, I've dabbled in Oly's (one per summer) and Sprints (1-3 per summer). I'm in good athletic shape, strong in running and cycling, and need lots of work in swimming. My Oly is in 6 weeks... All I can say is that I need to get my a** in the pool, and focus more on climbing for my one big climb on the bike course... other than that, I think I'm doing pretty good on my training.

Yesterday I ran a half-marathon and in the elation of my runner's high, signed myself up for a HIM only three weeks after my Oly. It's the Boulder Peak and the Boulder 5430 Long Course. Not sure what I was thinking, as there is another long course in CO in mid-September that would have been better for timing, but I got a little carried away and went ahead with the registration.....Yikes!

Overall my training has been 3 runs/week (each about 45-60 minutes), 3 bike/week (1 long ride about 35-40 miles, and 2 shorter rides about 12 miles), swims per week has been sporadic at best.

My goal plan is: Monday (60" swim). Tuesday (Run 45"). Wednesday (60" swim. 60" Ride). Thursday (45" run). Friday (Bike 60". Swim 60"). Saturday (Endurance Brick 2-3 hours). Sunday (alternate Run & Bike, 2 hrs.)

So... with what I've been doing and what I'd like to commit to doing.... do you think this is doable? I am OK with saying that I just want to finish the race but I also don't want to be the last one on the course. Thoughts?! Your input is much appreciated!!!
