I ran my fastest marathon in the rain.
Age 50 is a lot tougher than 40s
I also feel it usually takes four or five races to hit your best marathon for your body to be accustomed to the training AND the race itself.
I believe in keeping running simple and, in regard to shoes, that would mean no gimmicks, unnecessary cushioning, etc
The marathon can humble you.
Aiming for the marathon is a task of sorts which can include terrific highs and lows.
