You might enjoy your favorite foods or a day off on your birthday.
But a West Des Moines man rewarded himself in a different way.
He ran 40 miles on his 40th birthday!
David Larson has run between 10 to 12 marathons in the past decade, but this was his longest run yet!
He spent the past few months training and ran the 40 miles in about 7 hours Sunday.
It really wasn't too tough because for part of it I had my son who was running or biking next to me, I had my nieces who were running next to me, I had my Facebook page blew up, bet I have 100 messages on there so that's really motivating knowing that all my friends and family posting on my page like that.
