Countdown to Training, Base Building Continues

I'm trying to do my best to keep up 5-6 workouts per week in order to get my body and mind used to so much training. Between work, the weather, and feeling sore/tired it has been a bit of a struggle. I did two OTF workouts this past week, with a slow three-mile run in between. After doing hill work during the first OTF workout my calves were burning on my run. It was also a warm 75 degrees out (although very little, if any, humidity), which also contributed to my 10:48 average pace. My knee started bothering me a bit after that run, and the next day, during my second OTF workout of the week, my shin and calf also began bothering me, so I opted out of a planned Saturday morning long run. I think I need to start wearing my knee brace constantly, even for the OTF workouts, and to even buy a second for my right knee to wear consistently. Used to be that I would have to wear just the left knee brace for anything longer than a 6 mile run. Now, it seems that since I've upped my training, the right knee has been giving me a bit of a problem as well, and I'd rather be safe than sorry and just give myself a little more stability early on than risk injury or pain that could later hamper my training plan. Speaking of which, my 13-week Half IM training starts two weeks from tomorrow. I haven't been in the pool in a few weeks, and had my only outdoor ride on the bike one week ago today. This weather has been the pits this past weekend though, and I'm finding it hard to get out and ride or run in the ever-returning chilly weather. This concerns me a bit for when September comes along and that last month of training leading up to IMLOU in October hits it's peak. I'm starting to get a little worried that IMLOU will be cold, and how that will affect my race. Regardless, it's too late now to back out and I wouldn't even if I wanted to. I am still looking forward to achieving this awesome race, and look forward to Muncie as a "warm up" to see what I will need to continue to focus on to have a successful first IM.
