Veronica,
I can't think of a neater guy to support than Homey. He's just a treasure for those of us who know him. The good news is that he's done this before (twice, I believe) and knows what it takes to be successful. Who is he riding the tandem with? Same lady he did 508 with? I believe they did quite well on that race too.

Yes, I agree, you will be wiped out. It's a lot of work especially because you become the "mind" for the cyclists. They need your rational decisions to guide them on the route as well as making sure they eat and rest properly. You and Thom are strong people and that's what it will take to be crew.

How exciting and what a huge challenge. We'll be with you in spirit!
