I’ve started using this site www.fetcheveryone.com. As well as the usual race chat forums, race diaries etc. you can maintain your race portfolio, training logs, even graph diet and shoe mileage. You automatically get overall and age adjusted rankings and you can even bet (just points) on other members getting pbs. Surprisingly addictive and probably a waste of quality training time but quite a laugh. Unlike the athleticsdata site all standards are catered for.
