How does The Bluewater International Granfondo (BIG) work?

The BIG is a large group ride with several timed sections. Riders can choose between different course lengths. Riders can ride at their own pace with the goal to finish or compete for best time over the timed sections.

How is the course timed?

We use a proven timing system used in national championship events. Each rider will get a chip and be timed as they cross through timing sections. Splits will be recorded and posted at the event and online.  The 150 kilometer route has 4 timed sections, the 100 kilometer route has 2 timed sections, and the 50 Kilometer route has 1 timed section. Timing chips must be returned. Failure to return chips will result in a charge.

If I can’t finish what do I do?

If you feel like you cannot finish, take one of the shorter routes back.  There will be a Support and Gear wagon (SAG) or commonly know as the broom wagon that can give a ride back to the finish area, however, this vehicle will stay behind the last rider and will not provide immediate transport back.

Is Mechanical Support provided

Roving mechanical support is offered but be prepared to fix your own flats as you may have to wait longer for the roving support than it will take to fix it yourself.

Is my Entry Fee Tax-Deductable?

No, your entry fee is not tax-receipted. Additional donations to the two Charities that we support will be receipted by these charities.

Is there a mass start?

No. Each route will have its own start time specifically designed to avoid mass start anxiety and allow riders of all routes to be able to finish within a reasonable time of each other.

This structure allows for the focus to be about enjoyment while allowing your competitive juices to flow during the timed sections. It also allows for regrouping with friends in between the timed sections or riding your own comfortable pace.

Is there a minimum age for participation?

Yes, Riders must be 16 years of age by July 31st 2016 to participate.

Is there a time cut-off?

Yes, there are cut off times for timed sections and overall. The cut-off times are based on maintaining a minimum average progression speed (note: this is not average ride speed, this is progression average and includes all stopped time).

This is done for rider safety and to be respectful to on-course volunteers whose hard work makes the BIG a success. All timed sections are open for specific durations, you must enter and exit each time section during the specified scheduled time each section is open.  This is figured on maintaining an average progression speed of 20 kph for THE BLUEWATER 150K and THE LAMBTON 100K and 15 kph for THE SARNIA 50K.

Is there food provided?

Yes, at Fuel Stations and after the finish we supply hot food, but we also recommend checking out a real meal in the downtown areas.

Rain or shine?


Refunds or transfers?

No refunds but transfers will be granted if you cannot participate in the event.
