Tri Challenge in Hawaii: High spirits on Day One

This week, the CNN Fit Nation Triathlon team is in Kona, Hawaii, for a week of intense training. Follow along on The Chart and on Twitter, @CNNFitNation . Kas Seerla is a participant in the 2011 CNN Fit Nation Challenge.  She lives in Chicago with her husband and two young daughters, and is using this challenge to show other moms that it's OK to step out of their comfort zones!

Day One at CNN Hawaii boot camp! After a one-hour open water swim drill, we had to do a three-mile run around the beautiful Mauna Lani property. It was getting hot and the sun was above us at 8 a.m. I was nervous as I had never run after a swim but I was also in high spirits; I wasn't intimidated with a 3-mile run as I would have been a couple of months ago.

The guys took off and were way ahead but I was able to keep my pace and was right behind them when we completed the three miles. What a relief!

Onto the 20-mile bike ride after breakfast! I rode my bike outside the first time last week and it was only for 2 miles. So 20 miles should be interesting!
