Winchester Speedpark is located on Rte 10 in the Beautiful Monadnock  Valley.  WSP offers the "Best of Both Worlds" with two parks adjacent to one another off rte 10 in Winchester.  The Original Park has hosted racing since the 50's and was converted to a Supercross track, racing Saturday nights under the lights.  The park is situated at the base of "Rattle Snake Mountain" on 14 acres with a 2 1/2 acre Supercross arena Track with a playground, large Building used for sign up, arcades, concessions "The Kick Stand" and restroom facilities.  The track was designed and Built by Professional AMA Supercross track builders Dirt Wurx - Rich and his crew head to New Hampshire each spring to completely redesign the layout to create a fresh challenge for our racers to conquer!  This year is no exception, it looks like the best track yet!  Our goal is to bring the "Big Show" here to New England with professional attention to all aspects of Supercross so when it's time for the main event, and the lights go on, it's as if you're there. Weather you're a brand new 50cc rider or a New England Pro, you can feel like you're lined up next to Ricky Carmichael.  With our new announcer, Donn Collings bringing the crowd into the race, we'll be sure to catch all of the non-stop action.
