I wish Webb the best and hope that the running community will show him more support.
If you had the chance to talk with Webb right now, what would you tell him? That he should stick a fork in his leg, because he is done? I definitely would not.
I would encourage him.
I would point to athletes who have had incredible success at later stages in their careers. Webb is only 26. El G won 2 golds in '04 when he was about 30. Lagat doubled at the world championships in '07 when he was about 33. KD, who is still running well, ran 1:43 for 800 in '06 when he was 30.
A bright future can still be ahead for Webb! I would suggest for the running community to not make Webb's disappointment for failing to meet expectations any worse than what he is feeling internally.
On a small level, I can relate to Webb because of the pressure, stress, and disappointment I felt after failing to live up to expectations when years ago I lost the state championship in 1600m after entering the race as the top seed. I simply had a bad race - I got sixth I think. But I felt miserable about it for months. I'm so grateful for kind people who supported me when I was down.
Webb, despite in inconsistency, is undeniably one of the most talented American mid-distance runners ever, and I hope that the community can do everything possible to support and encourage him to reach his potential. Maybe he should join Rupp and Ritz in training... maybe he should lose 10-15 pounds... whatever the answers are for him to get back on track, I believe that he is more likely to find and implement them with the support of many good people in the running community.
