It's addictive.
The more you go to the gym, the more you want to go to the gym. Worked hard today - did the cross-trainer (OMG!) for about 5 miles, then 11 miles on the bike and some weights. Our sitter is coming over tomorrow instead of Sunday so we'll be on the road again... just so we don't forget what it feels like :) Hoping to do another half-marathon distance, but we'll see how it goes .... oh, and William still loves Tae Kwon Do :D
