Pre-Race

Took the plunge

After weeks of pondering over whether I am ready or not, I got a text from the Ironman organisation informing me that the Dallas Ironman registration is open. I browsed the site, added the race to the cart and talked myself out of it, thinking I will register when my friends Moni and Ila also sign up. Ila is a multiple Half Ironman podium finisher and Moni is a running beast. The 3 of us had decided when we met that we should sign up for Ironman together if we could make the logistics work (they are in India, I am in the US).

Went back to the ironman site a day later, pulled the trigger and signed up 😅. The deed is done. It set me back $600 including a $50 insurance which allows me to get a 75% refund within 7 days of race. I don't intend to use it, but it's nice to have in case of contingency.
