What are the youngest ages allowed in the BFC?

We recently received this query from a Black Fly friend:
Question:
What are the youngest ages allowed? And do they (the youngsters) race the entire course from Indian Lake to Inlet?
Answer:
While the BFC has no minimum age, EVERYONE that enters is expected to be capable of finishing the entire course in 4 hours or less.
The sweeper truck is instructed to arrive at the finish line by 3:30pm, which is 5 hours after the 10:30am start.
NOONE is allowed to remain on the course behind the sweeper truck.
