A few reminders….

Running with strollers is allowed – we ask that you run at the back of the ‘pack’.
Participating without registering (‘bandits’) is prohibited.
Those wishing to walk (non-competitive) the course are welcome to do so, but keep in mind; we employ a ‘rolling closure’ over the course. This means that the street closures/intersection traffic control have a time limit; additionally, the finish line/timing mat is removed from the street at approx. 11/11:30am in order to reopen the South End vehicular traffic.
Dogs are prohibited on the course and at our Hospitality Area – Strawbery Banke unless they are licensed service dogs.
Amplified sound/music on the course (transported on strollers, etc.) is prohibited; ear buds are not recommended.
