So, the triathlon went well. I finished it in 82 min, 21 sec, which was substantially better than my personal goal of 90 min.
I did the 400m swim in 10 min and 20 sec.
The 11.6 mile bike was somewhat challenging because of the hilly terrain (it was in the mountains - Asheville NC), and also because I used a heavy (but sturdy) mountain bike. I may buy a road bike in the fall. I did the ride in 46 min.
The 5km run I did in just over 22 min.
While the race was certainly a challenge, I feel like I could have pushed myself harder and am definitely looking forward to the next one, in about 2 months. I was tired but not wiped out at the end and could have probably kept going a little longer.
If you have ever thought about doing one of these, I recommend it. I would definitely train [which I did, about 75 minutes a day during the week and 125-150 min during Sat and Sun - I don't think this much is necessary] but it's definitely achievable.
