PULLMAN – The perks of being an Olympian aren’t lost on Diana Pickler. For instance, her shoe sponsor, Asics, is stitching her a special pair of spikes for Beijing, personalized with her name. On the night she made the team, she walked into a Eugene, Ore., pizza house with her family and received a standing ovation from the diners. Accessories and acclaim are fine, but the true bonus is realized mostly in her head, when she’s grinding out repeat 200-meter sprints on a lonesome track in the heat of a Pullman summer.
