Training Officially Begins

Well, I decided to go with a coach after all because I just feel that I need the discipline, expertise, accountability and custom plan to make this thing happen. I am now on day 4 out of the last 5 working out and I AM EXHAUSTED! 1500m swim Thursday, rest-day Friday, 40 mile bike Saturday followed by 20 min. walk, 1700y swim plus 6.42 mile run yesterday and another 1600m swim in the pool today. My body is sore and I've felt like I am about to fall asleep since arriving to work after the swim this morning. I'm definitely getting enough sleep (9 hours last night, probably 10 the night before) so I know it's not that. I'm assuming this is just my body getting use to doing so much in a short amount of time. I'm trying to do what a lot of people are telling me on Facebook, which is to just look at one training day at a time so as not to get overwhelmed, but I must say - Thursday's rest day is looking awful good right now. I have an hour bike tomorrow followed by a small run, and another swim on Wednesday before I get that much-needed break. And although this fatigue is definitely draining, I'm looking forward to all of this hard work paying off (and being well worth it) in October!
