KRASNAYA POLYANA, Russia (AP) The top U.S. Olympic women's bobsled sustained damage to its front end at after a fast training run Saturday.

Elana Meyers and brakeman Lauryn Williams completed their practice run down the Sanki Sliding Center course in 57.50 seconds - 0.34 seconds faster than any other sled - before banging a wall in the outrun. The pair did not take their second run so mechanics could fix the BMW-designed sled.

On Friday, Meyers crashed the sled at the bottom of the course on her first run. She and alternate brakeman Katie Eberling were uninjured and made a second run in USA-1 without incident, posting one of the session's fastest times.

USA-2 driver Jamie Greubel and alternate brakeman Kristi Koplin had the best time (58.13 seconds) in Saturday's second training run.

The women's competition begins Tuesday with two runs.
