Thanks for all the comments yesterday!
I woke up this morning bouncing off the walls ready to run a thousand miles. I feel rejuvenated with the Chicago monkey off my back and an epic challenge in front of me. But alas, it was 33 degrees and raining quite hard with a mix of sleet, so I did a 45:00 core and weight session instead. I have no problem training in crappy weather, I actually prefer it sometimes, but I still have to temper my enthusiasm. There's little point to a run in freezing rain. I am building up one of my bikes however to ride on my Computrainer for days like this. I will also be using the bike over the next year to train for Leadville. On days when I'm wasted tired I can still ride 2-3 hours at MAF and be better for it, where a run might be counter productive. Same goes for a heavy snow day where a long run might be senseless (we had 51" in 3 days last Winter). I've always felt that cross training on a bike wasn't very good for running speed, but with a race that's 100 miles there are other factors besides speed at play. My main focus for the next 5 months will be to build on top of the fitness I have now and come in to the Spring more aerobically (base) fit than I've ever dreamed of. My engine is very solid now off weeks of less than 100 miles. With a 100 mile race ahead however, and not a fast 26, I feel 'set free' of the rules I always followed that were based on how to run fast. My favorite period has always been the base period (it's also the most important one), but this one will have no limits... and I'm drooling. I always had 'key workouts' in front of me that kept me from running to real fatigue, even during a 140 mile week I didn't push it. I remember I ran 26 miles in 2:45 on the last day of that week which shows the level of fatigue I had. Now I feel like those old rules no longer apply as much. I have a ton to learn and a gazillion miles to run and it's going to be awesome and fun and brilliant.
I'm rambling now and could go on for another 10 pages I'm so excited.
