The 17th annual Limestone Century Bicycle Tour is a one-day classic century ride where it’s the distance, not speed, that counts! The tour starts and ends in the historic Portsmouth area of Kingston. Registration includes: rest stops, SAG (support and gear vehicle), meal voucher, draw prizes, and of course – FUN! Three route choices; 50 km, 100 km, and 161 km. This is a fundraising event for Cycle Kingston, a registered charity that promotes cycling and cycling safety.
