The Martin Richard Foundation’s third annual MR8K will take place virtually on Sat., Nov. 14 in partnership with the Boston Bruins Foundation, New Balance, and DMSE Sports. The virtual version will include a live race experience for runners to compete on the course of their choice. The event will take place Live and On Demand through a partnership with Charge Running, a platform that offers live virtual races with real-time feedback, including a live leaderboard, a DJ, and instant race results. The starting gun will sound at 9 a.m., but runners unable to participate in the live event will be able to compete and register their time through Sunday, Nov. 15. The event is open to runners, walkers and para-athletes of all abilities, as well as families with small children. Registration is $40 for adults and is now open at mr8k.org.
