The Limestone Century Tour Bicycle (LCBT) is an annual non-competitive cycling event for cyclists of all types and styles of riding. There are three distances choices - 100 mi, 100 km, or 50 km. The ride is fully supported, meaning rest stops and a SAG (support and gear) vehicle. A "classic century" tour is not a race, but rather an opportunity for riders to "ride the distance!"

Pre-ride check-in begins at 6:30 a.m. Riders are requested to arrive between 30-40 minutes before their start time window. Start time windows are based on distances: 100 miles between 7:15 a.m. & 7:45 a.m.; 100 km between 7:45 a.m. & 8:15 a.m.; 50 km between 8:15 a.m. & 8:45 a.m. Riders are asked to please start according to chosen distance. Riders will be sent off in groups within start time window for their distance. All riders must be on the road by 9 a.m.

Post-Ride Check-In

Upon return, riders are to check-in with a volunteer, so we know you have safely enjoyed the tour. Riders are encouraged to stay around long enough to welcome the next rider or group of riders. All participants should be back no later than 5:30 p.m., when on-route support ends.



This classic-style century tour has its roots in decades old tradition of recreational century rides. A non-competitive long distance, one-day bicycle tour for anyone who wishes to participate in this kind of personal challenge of riding a bicycle for 100 miles in a day! In 2006, Hal Cain (at that time Kingston Velo Club's (KVC) Tour Director) wanted to revive this classic style century tour and offered it on the Club’s schedule in September (the traditional month for bicycle century rides). No doubt a bit lonely, Hal was the only rider to ride the 100 miles that year, and without support.


Over the next few years, more KVC members became interested and took on the challenge and the century ride became an annual event. To be more inclusive of those who are not up to, or interested in, riding an imperial century, a 100-kilometer metric century route was added was added in 2010.


In 2012, a decision was made to make the century ride open to non-members as a community event -- with a registration fee and the addition of organized rest stops, support vehicle, and prize drawings, etc. It also became a fundraiser for Cycle Kingston. The following year, a 40-kilometer (25 miles) quarter century route was added to make it more inclusive. In 2015, the KVC Century was rebranded as the “Limestone Century Bicycle Tour” (LCBT) to reflect the geology and geography of the area. The 2018 version saw the 40 km route replaced with a 50 km, half metric, route.

After a dozen years of this century tour, a decision was made to not have the LCBT  part of the KVC official schedule. The LCBT is now under the auspice of Cycle Kingston.

Rain or Shine - It'll be Fine

The Limestone Century Tour is a "rain or shine" event. Over the years, we've had both! However, most riders will agree that no matter what the weather is like on the day, at the end of the day, it's a lot of fun!! And, the more "interesting" the weather the better the memories!
