Handling extreme G-forces. Physical and mental challenges. Split-second reaction skills. These are traits that every good Formula One driver has.

But driving skills are not enough to cope with the demands in a sport that sees speeds up to over 300kmh.

The racers also go through a rigorous fitness regime - one that the public can now be a part of.

Race promoter Singapore GP is inviting Singaporeans and residents to take part in the first-ever Fit For Racing challenge.

Prizes worth over $24,000 await, such as The Green Room and Grandstand tickets to the 2015 Formula 1 Singapore Airlines Singapore Grand Prix from Sept 18 to 20.

The challenge - a Rev Up Singapore! initiative - aims to share the excitement of Formula One across the island through a fun but difficult challenge on Aug 22.

Participants will go through a circuit-style workout which focuses on core stability, balance, upper and lower body strength, reaction skills and full body muscular endurance.

The top 12 finalists - in the male and female categories - will battle it out in the finals where the top three from each segment can win prizes.

All other participants who successfully complete the challenges will also receive a limited edition Fit For Racing finisher pack.

In order to prepare for this challenge, there will be an eight-week online fitness video series led by Paul Haines. The Australian fitness coach has trained elite athletes including F1 driver Daniel Ricciardo.

Pairing up with Haines is Singapore's only female race driver, Claire Jedrek. They both will give viewers an insight to the training that Formula One racers go through, and also serve as mentors to aspiring participants on what to expect in the challenge.
