Another good reason to ride the road
Another good reason to ride the road: It’s reported that 200 mountain bikers in a race in Squamish, British Columbia, became ill from feces in mud on the course. “Campylobacter jejuni” was identified as the bug, causing diarrhea and abdominal cramps for 2-10 days. “All you could see were the whites of the riders’ eyes from the pictures we saw,” said a doctor, failing to mention any white teeth. After the race, an investigation of sick riders was conducted by Canadian health agencies.
