I was so inspired by Emmy's approach that I did the same last night. I did an extra few miles running around a dark, dank, extremely muddy wood. The GPS trace is quite amusing, I get within spitting distance of an exit and then turn around and head as far as possible from any exit. Brilliant. 
I also picked up a stowaway tick who was happy to take the free lift back to my place, delighted to share the shower with me, but then decided that my leg and blood wasn't quite good enough for it and crawled off, ungrateful git
So I smashed him with a golf ball
.... any points for ticks?
