Not me. I thought I had a heavy schedule this year. I remember the first year I did two marathons in one year. I thought that was pretty tough.
Check out Chihping Fu, I was thinking of posting to clarify that this dude is really running all of these 100's this year. Check out the dates too, many of them are a week apart. Personally, I would be cool just with a name like Chihping Fu. Although, it lends better to golfing "chipping fool".
Like Keith, I have a full blown case of Afton fever. I even took the time last night to have great diet prep for the race. I had some people over and we ate brats, baked beans, home brew, and I had a piece of French Silk Pie. I topped it off by only sleeping 5.5 hours. I tried to sleep in, but my body likes the 5am hour. It is all okay. I can take a nap today. Sleep is over rated for these runs, and I will have a great day tomorrow.
