Copied from an anonymous poster on FB Capital Trail Roadies. I have no more details. Be safe. Keep your speed under control. Be aware of others. Set a good example.
"There was a major head-on bike on bike crash at MM 1 this (Thursday) morning. One bike rider taken to Hospital (Trauma Center). Just a reminder to all out there about trail safety. The curves and bends and typical high volume of bikers, walkers, runners, etc. between MM 0 and ~MM 4 can, at times, be a challenging combination. Be aware and mindful, keep your head on a swivel, and be ever mindful for those call outs (e.g. "On your left", "rider up", etc.). And bikers, please always wear a helmet! I can almost undoubtedly say a helmet may well have saved two individual's lives today! (Helmet = Done... Head inside Helmet = intact)."
