Does anyone know of a web site that lists US and/or world marathon age group
records. I'm looking for 5-year age group records for both men & women from
20-4 through (at least) 65+.
I've found some sites. One lists US & world road racing records for 5-year
masters age groups. Another lists best performances in the marathon for open
and masters. I could possibly pull together what I want from multiple sites.
But, there are some discrepancies, open records aren't differentiated by age
groups, and I'd like one definitive source.
