We were delighted to have Nina's first blog for BOING in September 2014 when she announced her intention to become the youngest person to cross Antarctica in memory of her sister Verity who died of cancer in 2009 and in the to process raise recognition of her Mum’s fantastic charity "The Teapot Trust", which provides art-therapy for sick children in hospital.When we last heard she was training very hard and was seen alongside Sir Ranulph Fiennes.View her earlier inspirational blog and images in our September 2014 blog archive.

I am very pleased to be able to do an update for BOING, who make great outdoor rope bracelets and which I enjoy wearing a lot.2015 has flown by so quickly. After an awaited trip to visit family in New Zealand in January, we were able to visit the awesome Mount Cook Mountain and experience some of the iconic Kiwi scenery. Trekking on the Tasman Glacier really brought home the effect that global warming is having on ice-capped areas, as the glacier was riveted with hundreds of deep crevasses created by melt-water that made walking difficult.

My Mum’s great friend Jan Arnold met up with us in Hamner Springs, near Christchurch. Jan’s husband was Rob Hall, the climber and mountain guide who died on Everest during the terrible storm of 1996. Jan was often the expedition doctor, and she gave us excellent advice on coping during an expedition, especially in the cold.

Unfortunately however, the preparation for my trek across Antarctica has not entirely gone to plan. Recently I have been diagnosed with Raynauds, a condition associated with Beçhet’s Syndrome, that causes a spasm of the blood vessels. This restricts the blood flow to the extremities, making them go white, which puts me at an increased risk of frostbite. Doctors have ruled out a trip on the grounds that it would be extremely foolish to be exposed to such low temperatures for an extended period of time, as there is such a high risk of me losing my hands and feet. Regrettably, a traverse of Antarctica would be impossible for me at the moment.

This has not stopped me training though, as I still plan to undertake an expedition or challenge in the future to raise funds and awareness for my Mum’s inspirational charity the ‘Teapot Trust’. The charity has gone from strength to strength this year, but has overall had over 5,000 art therapy interactions with sick children all over the UK during 2015 and has recently won the Best Charity award (turnover of under 250,000 pounds a year).

May brought round our annual camping trip to the Lake District. Swimming in waterfalls, wild camping, hill running and hiking was great fun.

In August, my Dad and I planned to climb the Cuillin Ridge in Skye. We were all set for a two day traverse, when the weather closed in. Luckily, we were able to complete half of the Cuillins, known as Pinnacle Ridge, before the weather arrived. Even with most of the view obscured by fog, the awe of the Ridge that we’d first experienced last summer was still breathtaking. Repeated scrambling was interrupted by abseils and steep scree slopes - difficult terrain but incredible to climb. I hope to return and complete it some day.

Instead of climbing the Ridge for the second day, we went cliff climbing on the coast, which was definitely worth it. On the coast, the weather was perfect, and the whole family completed severe grade climbs along the cliffs. We even saw a basking shark!

Regular visits to the Edinburgh International Climbing Arena has allowed us to develop our climbing skills. We are incredibly lucky to live so close to such amazing facilities.

The sea especially has been a great asset. With my new love of triathlon, great open water swimming is right on our doorstep. Dad and I swam regularly in the sea right up until November, but the North Sea now is very cold! We managed a swim on Christmas Day, but out toes (mine especially) were blue by the end.

I have really enjoyed running and cycling too, and hope to be selected for the junior Lothian’s regional triathlon development squad. It is hard to balance training and studying though, especially with GCSEs coming up in the summer. Despite training setbacks due to revising for mocks and seemingly catching every bug going around, I hope to get fitter in 2016.

I don’t know yet if Raynauds will be extremely limiting during cold conditions. Even though it’s a regular nuisance when swimming in the sea (swimming with feelingless fingers is painful), wearing the right clothing in the snow should prevent it from doing any permanent damage. In February, I will be part of my school expedition recreating the Heroes of the Telemark expedition. Not only will this help assess whether my Raynauds will be a particular problem in the cold, but it will also be an incredible experience to honour the efforts of those amazing heroes. During the Second World War, a team of British and Norwegian allies successfully blew up the German heavy water plant in the Telemark region of Norway, preventing the Nazis from developing the atom bomb. Our expedition party of 11 will cross country ski the original route of the team for 5 days and stay in the original huts used by the Telemark team.

Bring on 2016 and thank you BOING for your support, I still wear my bracelets while training.
