Wales This Week - The White Ice Cycle, Tuesday after News At Ten, on ITV Cymru Wales
An adventurer from the Vale of Glamorgan has achieved a world first by cycling to the South Pole from the edge of the continent in just 10 days. Maria Leijerstam managed the feat this Friday morning following a gruelling 500 mile ride in "vicious" conditions.
The 35-year-old set off from the Novo Russian air force base on December 16 and went head to head against two other male riders. Her team said at one point the sweat on the inside of her boots froze and she heated her freeze-dried food by melting snow on a small stove inside her wind blasted tent.
However, the former management consultant dug deep and pedalled her way into the record books while on a customised recumbent bike PolarCycle. Ms Leijerstam's mother Adrianne said her daughter's success was due to "meticulous planning, super fitness and pure determination".
Before setting out on her journey the extreme cyclist said: "I've had to get my body prepared for burning fat and not carbohydrates, so I've been training for two to three hours on an empty stomach which teaches my body to become more efficient."
It's Christmas Day but for Maria it means another hard day of cycling.
She's cycled 81km per day. On a continent where it never gets dark she has spent as little time as possible sleeping and maximum time she can cycling.
Maria is determined to reach the South Pole within the next three days.
In her blog yesterday she described the Antartica as vicious but beautiful.

Welsh adventurer Maria Leijerstam is well ahead of her two male rivals in the race to claim a world first cycle title this Christmas.
Although Maria, 35, from the Vale of Glamorgan started days later and took a different route to the South Pole from the edge of the continent, her average of 40 km per day is putting her well in the running for a first.
With over 45kg of food and fuel, Maria started her journey started on 17th December.
After the first 80km she spent two days cycling up the Leverett glacier against very strong wind.
Fresh snow is making the task difficult and increasing the drag but she is continuing to travel 40-60 km per day.
She will spend both Christmas day and New Years day cycling in temperatures as low as minus 40 degrees with the aim of reaching the South Pole by 7th January 2014.

Assembly Members have voted in favour of plans to radically reform support for cyclists and walkers, to encourage more healthy lifestyles. The new law is said to be a world first.
It would force local authorities to consider the needs of both walkers and those on bikes as they plan transport networks. The Active Travel (Wales) Act also calls on Welsh Ministers and Councils to promote active travel and provide annual updates to the Welsh Assembly.
Jane Lorimer, National Director of Sustrans Cymru, said “The passing of this legislation shows that Wales’ leadership is serious about making walking and cycling the normal choice for more of our everyday shorter journeys."

The Executive Director of Disability Sport Wales says Mark Colbourne has made an 'incredible impact' on the world of paracycling.
Colbourne announced his retirement from the sport today.

His record speaks for itself. He is a world class rider and will be a sad loss to British and Welsh sport.
Mark has also been the perfect role model, inspiring many young riders to further their own personal goals. In this sense Mark is an important part of our legacy and we hope that he will continue to act in an ambassadorial role for Disability Sport Wales and continue to help us to inspire a new generation of athletes.
