Mark your calendar and register for the 19th annual Limestone Century Bicycle Tour (LCBT) – Sunday, September 14, 2025! This one-day classic cycling century starts and ends in historic Portsmouth Village – Kingston, ON. It’s about the distance not time - not a race. The LCBT is an open community ride, all riders are welcome!

There are three great routes to choose from: 100 mi (161 km), 100 km, & 50 km. All routes go through a bit of urban leaving and returning to Kingston, but mostly on scenic country roads that pass-through villages. The 100 km and 161 km routes return along the shores of Lake Ontario. Part of the 50 km route is on the K&P Rail Trail, which is mostly flat and packed stone dust surface flanked by fields, trees, and rock-cuts.
