Count this one as a fail in the “considered the biomechanics” column. A 34″ wide cardboard almost-triangle doesn’t leave much margin for swinging the arms or, you know, breathing. A few snips and some bending got it workable. Lots of grins on the out-and-back leg of the 10K-only portion. And a whole lot of people saying they love me! OK, it. They said, “Love it!” That’s close.
