Molly Shaffer Van Houweling returns to the track, besting the U.S. women's hour record she previously set in December

American Molly Shaffer Van Houweling took to the track in Aguascalientes, Mexico, just hours after Thomas Dekker‘s unsuccessful run at the men’s hour record, and set a new best mark for U.S. and Pan-American women, riding 45.637km on Wednesday.

She characterized her December 15 tilt at the hour as “pretty miserable.” At the end of 2014, she rode 44.173km to set a new U.S. elite women’s record in Los Angeles. Nevertheless, Van Houweling traveled to Mexico for another attempt. Aiming to take advantage of high altitude and a track that was newly resurfaced for Dekker’s ride, she hoped to set a world masters record for the 40-44 age group and to extend her U.S. elite record. And that’s just what she did.

Her ride was 1.464km better than her American record, set in December, and Van Houweling, 41, crushed the masters 40-44 world record — previously set by Briton Auriell Forrester in 1998 — by 4.926km. Van Houweling’s previous ride would have set the master’s world record, but UCI officials were not present to verify it.

“I was also curious to see how close I could come to Leontien van Moorsel’s elite world record (46.065km), which of course might soon be extended by Sarah Storey [on Saturday in London],” Van Houweling told VeloNews via email. “I’m not actually eligible to set the UCI elite mark now because I’m not enrolled in the biological passport program. Enrolling in the program presents a formidable financial and logistical barrier for women and amateurs (who, unlike ProTour men, are not automatically enrolled in the program). So before even considering it I want to know whether the elite record is a realistic goal.”

Van Houweling was just 428 meters shy of the 2003 world mark, which van Moorsel set on a traditional drop-bar bike, not a pursuit bike that the Californian rode on Wednesday.

“I see room for improvement in my performance,” she wrote. “As is so often the case in a time trial (and despite repeated warnings by my coach Dave Jordaan and other wise advisers), I wonder in retrospect whether I went out too hard. It’s so easy to diagnose that mistake when others make it — as Jack Bobridge seemed to in his recent failed attempt. But it’s still so difficult to resist doing the same thing yourself on race day! I was probably too far ahead of schedule for the first 20 minutes or so. I fell off the pace after that until picking it up and really emptying the tank in the last 10 minutes.

“I could also still improve my track skills. I’ve been training occasionally at the Hellyer outdoor 335m velodrome in San Jose [California] since October and also did some training at the 250m indoor velodrome in Palma, Mallorca, over the winter holidays. But altogether I think I’ve trained on an indoor 250m track like Aguascalientes only about a dozen times. So riding the black line still isn’t effortless for me. I paid the price for my imprecision yesterday by running over lots of sponges that mark the edge of the track. That probably cost me meters and energy I would like to have back!”
