Hi. I just finished my first tri this weekend and struggled with some of the same things. I waited at the back of the pack for the swim when that is my strongest sport. I was immediately frustrated because I couldn't pass anybody. The transition was not so great because I forgot my towel! The biking was somewhat chilly with wet socks and clothes which were supposed to dry fast. I started the run and a 1/2 mile into it I pulled my achilles tendon and had to walk the remainder. I almost walked off the course but it was the other participants that made me stay with their encouraging remarks. tri people are really nice. It was kind of comical though because I couldn't even walk briskly so I didn't even break of sweat. The volunteers at the finish line were looking at me with a bewildered look given I wasn't sweaty and huffing and puffing. I would love advice if anyone has any about transitioning from the bike to the run. I have been having major problems with my calves, achilles, whatever getting pulled. I'm wondering if I'm not stretching enough or I need to do strengthening exercises. Thanks. Liz
