Matthew McConaughey hit the pavement with dozens of runners in LA yesterday taking part in his own j.k.livin charity event encouraging youth into leading active lifestyles. MM kept his shirt on for the race though we did get a good look at his rockin abs during a surf session and they came up again with Matt Damon's famous impression on Letterman on Tuesday. MM will have another chance to cheer on joggers later this month at the LA Rock n' Roll half marathon or perhaps before then while chasing after his almost-walking ballerina and freewheeling toddler. The festive family has a few weeks left to hit up the pumpkin patch before Vida's first Halloween though, Matthew's already been testing out spooky costumes for the big night.
