There's a bit of singletrack that runs through the woods at the side of the motorway, good fast bit of path, but is also popular with dog walkers. There seems to have been a hatch of some chunky long legged jet black flies just recently, and they fit just nicely into a helmet vent. Yesterday I was tanking along, trying to ignore the wriggling that was going on under my helmet (ping Fnaaaar!) when something went down the front of my shirt. That's OK I thought, I can just kill it and keep going, so I slapped at where I guessed it was, only to discover that whatever it was could sting, and appeared to have got under the front of my bibshorts. This called for a change of plan, so with all the aplomb I could muster I slammed the brakes on, leaped of the bike, ripped my shirt off over my head only to discover that I couldn't get it off over my helmet, and the thing wriggling around in there made me think I had to get that off in case that could sting as well. Thing was, I was wearing full-fingered gloves and the material of the shirt over my head was now stopping me getting to the buckle. Several seconds of swearing and panicking eventually saw me emerge from under the shirt to look straight at two women dog walkers who had appeared from around the next bend. The word "wasp" was enough to convince them that I hadn't escaped from my carer momentarily, but no doubt that their opinion of mountainbikers will have been amended just a tad.
