Rrrruffles Have Rrrridges | Road Course Measurement Forums

jimgerweckMember

Some of us remember that old potato chip ad.
To the point: I measured a course on a major road that had a 2-3 foot wide shoulder. Just outside the lane line (on the shoulder) the surface had been milled with a continuous series of inch deep depressions nearly a foot wide to create a "rumble strip" to alert sleepy or inattentive drivers that they are veering off the road.
There is no way anyone could run on this surface without seriously injuring themselves so I measured 20 cm off these depressions rather than the edge of the road. My feeling is they create a curb even if depressed rather than raised. Thoughts?

I've faced that situation also. I probably thought about some of the bolder runners in the area and just went ahead to measure over the rumble area. But now I think maybe stay off of it but you'd have to put cones etc for some runners I know!

There is no way I would run, or measure, on those rumble strips! The measurement would not be accurate, anyway.
