At 73 ( soon to be 74 for masters purposes) attempts at records are a long way away. If I can live to be 90 and manage not to slow down I may have a chance.
There's always the personal record, of course, and up till now they have fallen at a satisfactory rate. I heard a clubmate muse wistfully after a race recently
"The older I get, the faster I used to be"
He's only a lad of 49 as well.
