Hi Frank,
Glad to hear the good news. You're doing better with riding than I was when my chemo had just finished up 5 yrs ago. Went for a ride a month later with a friend on a really flat trail (Capoolong Creek Trail). Felt good for about 1/2 mile, then completely and totally bonked out. Turned around (with the bike in granny gear on flat ground mind you) and rode for about 200 ft before I could go no more. Picked out a tree about 150 ft away and told myself "... just make it to there". I would then struggle to get to that landmark and stop exhausted for a 2 minute rest before I could continue. That repeated itself over and over every 100ft or so until I got back to the car. Took me at least 1/2 hour to make the 1/2 mile trip back. Hated it, but kept at it whenever I could get a chance. At the time it felt the worst part of the whole cancer experience. Took me about 6 months to even get close to where I was prior to the chemo.
Really happy to see you back on the bike too. You are (and have been) in myself and Sue's prayers. Hope we see you on the trails sometime soon.
PS: Not sure you remember me, but I'm the guy you had to carry to your van when I broke my hip 3 yrs ago. Always grateful for the help you gave me back then.
