I thought I'd heard that Chad Kellogg was climbing in China. Not very likely that he'll fly all the way back to the U.S. just to perform for Dan Howitt.
And, besides, Dan, we're already growing weary of the constant challenges for speed climbs. There are plenty of opportunities for both Howitt and Kellogg to compete in regularly scheduled races without hype, drama, or innuendo. Yet neither has done so. To the general public, there are two likely reasons for their lack of participation - 1) They don't care about racing others, or 2) They don't want others to be able to observe them as they attempt a speed climb. I suspect that both Howitt's and Kellogg's motivations are covered by these two reasons.
And, as a side note, the above post was made by a Jim Kiltenship. Odd, isn't it, that a google search reveals absolutely zero entries for the word Kiltenship. I suspect that Dan Howitt has added yet another entry to his long list of aliases.
