+1, Dave -- on both posts.
You know, I've been mulling this over and wanted to ask here as opposed to a cycling forum for the very reason that there are triathletes here and runners.
If the network were broken down into thirds, it could work.
1) Cycling
2) Triathlons
3) Running
Between the three, sponsorship would be a breeze. I mean there's more events going on than we know of: for instance, the Tour of Ireland is coming up. Versus will cover it, and that's because Lance and Alberto will be there.
But you're correct about Americans and their ignorance toward pro-cycling. It's not ball-through-hoop simplicity or ball-whacked-with-bat stuff, so they tune it out or don't care or ridicule it.
I remember when Jack Kemp called soccer "...a commie sport."
