Roadkill Takes on Karknocker 5k Posted byJoshua Perks August 5, 2013 Leave a comment on Roadkill Takes on Karknocker 5k FacebookTweetPinEmail As is fairly typical for this blog, I’ve fallen way behind. In order to get caught up I’ve decided to post some pictures from the Karknocker 5k. Everything you need to know is in the captions and the results. Ready Set Go. Holding on. Trying hard to breath.
