here is one point of view on twice-a-day runs… http://www.pfitzinger.com/labreports/twoadays.shtml
sometimes i do doubles, usually with shorter distances, when i cannot wait for the next day to run again. you know, that feeling of “i gotta get out there and run!”…
what is your opinion on twice-a-day runs?
they are great; i do them all the time
they are a great idea, but i never do them
they are an invitation to injury
they are just “junk miles”
run twice a day? why?
good idea, off i go!
other (explain in comments, please)
