The exciting ninth annual Bluewater International Granfondo welcomes cyclists to Lambton County’s Bluewaterland, starting and finishing in the City of Sarnia’s beautiful Mike Weir Park.

There are four routes to choose from all of which will take in some outstanding views of Lambton County with the finish for all routes being along the stunning shores of Lake Huron. The four routes are 30k, (family) 50K, 100K, and 150K each with their own start time specifically designed to avoid mass start anxiety and allow riders of all routes to finish within a reasonable time of each other. B.I.G. utilizes timed sections which is a format that prevents chaotic starts but still allows competitive juices to flow. This format allows all riders to receive a competition time for the timed sections (no overall time will be given) while also being able to take your time in between timed sections and regroup with friends upon completion of the timed sections. Riders can cool off with a refreshing swim in Lake Huron prior to relaxing to a live band while enjoying a well-deserved beer or soft drink along with some very tasty food.

Whether you are looking to experience the enjoyment of riding on quite country roads or through thriving fruit orchards or challenge yourself on the rolling hills of Arkona you will find it all in this area of outstanding natural beauty. For more info visit www.bigf.ca
