When I'm 51yrs old

Apparently it takes 6 yrs of training to build up the kind of strength to cycle strongly at the end of the race and to kayak that far. My running legs should be ok thankfully as after all those years of stumbling around the roads, hills and mud I can get myself into decent shape for long distance stuff (not PB shape of course) in a matter of a few months. Trouble is, all that running has done for me is to help lose 2 inches off chest and the (even if I do say myself) toned lats, pecs, deltoids, etc etc. All that living in Surrey and Leicestershire has reduced my leg strength to zilch.

I'm not giving up hope though as (according to the above theory) when I reach 51yrs I should be well prepared and strong enough for doing this type of endurance race (45 at moment). What sort of shape my body (joints etc) will be in by then is rather questionable of course!
