TNTT – Thursday Night Time Trials @ Markham, ON
May 23 all-day

A weekly Time Trial series on a 15km course located in Markham, ON.

For nearly 10 years now RealDeal have run a weekly time trial series called the TNTT. (Thursday Night Time Trial) There was a TT held on what is now the TNTT course for many years before RealDeal arrived. It started with a few friends taking turns timing each other. RealDeal enjoyed that style for a few seasons then partnered up with Bob Haufler and the Midweek Cycling club to try and build the series into what it is today.  Two dreamers hoping to grow and share enjoyment of the sport with others each and every Thursday night. What was once 6-8 riders self timing each other is now the biggest and best weekly TT series in the GTA.



Start line – Kennedy Rd and Elgin Mills  Finish line – Kennedy Rd just North of 19th Side Road

Parking – Melville Misson Church 11248 Kennedy Rd, Markham, ON L6C 1P1
