Lovely Shellcrusher!! I'm glad to see you followed through! Signing up for a class certainly helps motivate and keep you on task :-)
I used to run marathons, triathalons, and long distance bike races (100+ miles) but lost touch with those hobbies after meeting AH. I gotta get my runner legs back. I went running with a group of engineers this week and it felt A-MAZING! Funny to see this post today because that's exactly what one of my running friends said... "You need a MAJOR goal. Sign up for a marathon or triathalon! Pay the entry fee then you won't back out!"
So my goal for this year - run a marathon.
