Lucinda Martha Ruh (born 13 July 1979) is a Swiss former competitive figure skater.

In April 2003, Ruh set a Guinness world record for the most continuous upright spins on ice (105).

Although she initially enjoyed jumps, her interest in them waned as she grew to 5'9" (175.26 cm), "Since the center of gravity was higher, combined with the rigid training while growing, I never really had a chance to get my timing and balance back.

[1] In 1997, she worked with Christy Ness in San Francisco, California[6] but developed two Achilles tendinitis, a ruptured shoulder and Sciatica.

In December, she moved to Switzerland, where she met coach Oliver Höner; it was the first time she had resided in her birth country.

[1] In the summer of 1999, she went to the U.S. and was briefly coached by Galina Zmievskaya but tore knee ligaments and returned to Switzerland for treatment.

On 3 April 2003, she set a world record for the most continuous upright spins on ice (105 revolutions) at the Rockefeller Plaza outdoor skating rink in New York City, beating the previous record of 60 revolutions[8] by British figure skater Neil Wilson.
