A colleague who rides with the club has just told me a member of the club died last night. newish member, riding in the front group, hit a sunken manhole (the result of recent resurfacing works apparently) and his bike broke into three pieces. He died instantly. An ambulance on another call was coming in the opposing traffic and stopped, but an hour of work failed to revive the guy. Father of three.
My colleague commented that that group rides "hell for leather" and no-one is leading the group or calling / keeping control (it's a small group apparently), and as a result he's dropped back to the "slower" following group to enjoy his riding.
Made me reflect again on the potential influence of Strava segments, PB's etc., which perhaps drives such groups to go ever faster.
Edit: I suspect that this would be the incident.
