NASCAR and motocross are about the only worse things I can think of to call a "sport" then speed "climbing". BUT, I did learn an interesting and absolutely rediculous fact from that Dan - driven website: 
  
"US mountain speed climbing raised to true sport status with my (Dan -) official speed records on the four tallest  glaciated volcanoes in the continental US:  Mt Shasta, Mt Rainier, Mt Hood, & Mt Adams.  These glacier volcanoes provide the most vertical relief (elevation gain) and the greatest difficulty and challenge for a speed climber... they are the most challenging mountains for speed climbing in the continental US." 
  
What a freakin' joke...somebody pat that guy on the back because he is just getting loopy from having to do it so much to himself.
