15 weeks until Ironman Arizona

I'm now 15 weeks away from IMAZ. This weekend I finished my 1st big brick workout for Ironman Arizona. Yesterday I did a 13.1 mile bike & a 9.7 mile run, today a 61 mile bike & a 3.4 mile run. My weight is maintaining around 185-188. Although I'm still struggling to fit in enough cycling I feel really good. I still feel confident in breaking the 13 hour mark. I probably wont be as close to 12 hours as I originally hoped, but I should hit my sub 13 hour mark.
