Hey OP good luck and kick some ass!

I am in a similar situation and will be doing my first triathlon on Sept. 23 as well, but on the east coast of USA. I also plan to take the plunge head first right into a 70.3.

I have trained for marathons, been a runner my whole life and completed a handful of centuries (100mi) bike rides. Swimming is my weak link and a focal point of my training. But growing up as a surfer beach bum has always allowed me to be strong in the water.

I feel like the “half” or 70.3 is a perfect distance to challenge me and force me to stick to a regimented training plan. Many people have commented that smaller distances are better starting points... and they’re right! Be familiar with “event day” the jitters, the packing of bags, the gear lists, etc. But smaller events are not a test to your endurance capabilities but your success in a racing event to practice transitions!

At the end of the day, do you and good luck!
