Maria Costello

Costello has won a total of eight Manx Grand Prix Silver Replicas and one TT Bronze Replica. These are trophies awarded only to those who finish within a percentage of the winner’s time.

In 2012 Costello also worked as an occasional guest instructor for The Bike Experience, a charity organisation dedicated to helping motorcycle riders who have suffered spinal damage to ride again.

The Discovery Channel's Big Big Bikes program featured Costello racing a Honda Fireblade motorcycle against a Porsche 911 GT3 RS. This programme, in the UK alone, was seen by a million viewers; the global release in 2006 reached audience figures of between ten and twenty million.

Costello was the first woman (solo racer) in the history of the Isle of Man motorcycle races to stand on the podium when she took third place in the Ultra Lightweight category of the 2005 Manx Grand Prix. Riding a Honda RVF400, Costello became the first woman to take a podium finish in either a TT or Manx GP. Her success as a female motorcycle racer and success on the track has attracted attention from the media and the motorsport industry.

In 2004 at the Isle of Man TT races Costello achieved a Guinness World Record by becoming the fastest woman to lap the Snaefell mountain course at an average speed of 114.73 mph. She also finished 8th in the Senior race of the Manx Grand Prix (collecting a Silver replica award) in a field of more than 80 competitors.

Costello has appeared in several television programmes including an Anglia TV documentary on her return to the TT races in 2002, and she was one of a few included on TT Heroes, which followed competitors during the 2003 TT. Recently Costello was a presenter on the motorcycle show Fran's Angels. She has also been a panellist on Top Ten Bikes, and has worked as a stunt double. She doubled for Tamzin Outhwaite on a mountain bike in an ITV drama Walk Away and I Stumble. Costello was the rider-double for Oscar-winning actress Reese Witherspoon and worked alongside the lead role played by Christina Ricci.

Costello has been contributing to the motorcycle press as a freelance journalist since her career in motorcycle racing began in 1995. Initially it was her race press releases that were published in the local newspapers but her ability on the racetrack led to an invitation to join Motorcycle News and Performance Bikes on road tests. She is now a regular contributor to the Used Bike Guide in addition to publications such as Irish Racer Magazine and Motorcycle Racer.
