31st Dirty Dozen Hill Race

The 31st annual Dirty Dozen race up Pittsburgh’s steepest hills, including Canton Ave which is recognized as the steepest street in the USA, is happening this coming Saturday after Thanksgiving as so many before it. Unsanctioned, just go. Is this the oldest “alleycat” in the country? Quite possibly, depending on definition.

Read about the Dirty Dozen in Urban Velo #5, and a profile on founder and legend Danny Chew in Urban Velo #10.

    Interesting how many macho cyclists were not using their granny gear up front. On my recumbent tadpole trike with its 11″ low gear I know I could get up any hill, albeit slowly! Did you notice that the guy on a balloon-tired mountain bike was spinning up fairly easily?

    As one of those balloon-tired mountainbikers – I could do that, but not fast. (In San Diego we compete to see who can climb what without uncliping. Cowles Mountian anyone?) Nice clip demonstrating that you can go over the handlebars whilst going up hill if you unload the rear tire. Well done!

    What was the steepest % gradient? This climb looks insane…

    Canton Avenue is 37%, if I remember correctly. That is the one near the end with the falling cyclists.

    How does this compare to Fargo Street in Los Angeles – a
    33% grade going up?
