Thats what I'm thinking Barly, i've spent 22 years running - that's the bit I can do. Over the last 6 years, I've had 2 kids and really only run so x-training has been at a minimum. I need to get the cycling muscles working.
and I'll mention again that I need to learn to swim properly!
Gumps, the running is the only thing I've got any confidence in.....
but I've got to be really mentally strong with this, and I can be - I just hope my body holds out!
