This weekend I have a hard 5 hour race sim on Saturday (late day effort) followed by a 2-3 hour race sim on Sunday (early day effort). I'm planning to do the Sunday race sim at a race - a local race here in Seattle which will be my first race of the season.
Crazy or good? I am going back and forth. But heck, you only live once and I am eager to race. Doing the race will ensure that I push harder than I otherwise wood. Doing a 5-hr (late day) race sim the day before will ensure that I am racing on 'tired legs'.
The best laid plans ... we will see :)
