A couple of years ago a cyclist died here from a collsion with a runner on the local trail. The runner was part of a college cross country team and made an abrupt turn and caused a collision. The cyclist who apparently always wore a helmet for some reason was not wearing one that day...and she did not call out as she was passing...died from her injuries. Pere Marquette trail Midland MI.
Sometimes if a trail peaks in the middle and slants to the side runners will pick the side that favors which ever knee or leg isn't hurting at the time. I understand that. But the running with ear buds-turning around without looking type of behavior is selfish and dangerous.
