I met with my new Peak Centre coach, Paul, yesterday to discuss my 2009 IMC training plan. Based on my lactate testing he concluded that I have a huge Z1 and a very squished up Z2-5. Basically, I can do long slow distances forever but really can't speed it up at all. He suggested doing a few 5km and 10km running races between now and March to build up my Z3.
His other suggestion was to do only one Half IM before IMC and it should be in late May or early June. Below are my choices...not sure which one will win out but I know that registration is filling up for all of them quickly!
