Hey sapper. all the best. i can't help with direct experience - just words of encouragement.

i suppose it depends how you react to your particular illness and your particular treatment - i don't know what stage you are or what prognosis you have been given/what treatment you are lining up for.

in the thick of it all, you'll know what constitutes an achievement - whether it be completing a race, making it round the block, or getting out of bed.

we can't all be jane tomlinsons or lance armstrongs - though we can be inspired by them, just run/walk what you can with the body you have that day.
