M is for Marathon

Marathon runners seem to always amaze me with
their agility to be able to run that distance.

1894  Marathon Greece a runner ran
 the scene of a victory over the Persians in 490 BC; the modern
 race is based on the tradition that a messenger ran from Marathon 
to Athens (22 miles) with the news. 
however, this was not a flat land there where hills and uneven terrain

Phidippides is the person who is responsible for our marathon

he not only ran the 26.5 miles to pronounce the victory

but prior ran 147 miles from Sparta to Athens to ask for help

with the Greecian people fighting in Marathon.
