Frequently Asked Questions

Held on August 2nd or 3rd in Sarnia, the event benefits from Lambton County's warm summer weather ideal for coastal cycling.[2][3]

Well-marked routes from Mike Weir Park feature multiple fuel stations, on-course bike support, ample free parking, and sharp start times like 7:45 AM for 100k.[3][4]

The 150k route covers ~93 miles through the scenic Bluewater region of Lambton County, featuring quiet country roads and rolling hills in Arkona along Lake Huron shores.[1][3]

Despite its Ontario #1 Granfondo ranking, the 10th edition remains a regional Lambton County event without international pro field draw.[1][3]
