For many people, suffering a deep vein thrombosis might be a prompt to take life a little easier and not put the body under any more strain.
Not Jude Murray.
The Aberdeen woman is taking on a string of ever more arduous endurance events to raise funds for a charity which is seeking to find a cure for the condition.
Her most recent triumph was in completing the Ythan Challenge – an 11km multi-terrain adventure race held at Ellon every year.
It was the latest – but by no means the last – in a series of daunting activities, which involve her travelling the length and breadth of the country in aid of Thrombosis UK.
Ms Murray experienced her first blood clot – in her liver – at birth, and has suffered the effects of portal vein thrombosis all her life.
She made regular trips to King’s College Hospital, London, throughout her childhood, and spent her 18th birthday in Hope Hospital, Salford, during a seven-month stay.
In summer 2013, she had a significant deep vein thrombosis in her thigh and will be on medication to prevent more clots for the rest of her life.
Despite the pain she suffers from post thrombotic syndrome affecting her everyday life, she is determined to push herself to the limit in order to help others.
She said: “I have realised how little is known about conditions such as these, both by medical professionals and the public.
“Quality of medical care, treatment and understanding has been variable.
“Public knowledge is also limited and I would like to raise awareness to help someone identify any potential symptoms and know how to seek advice.”
The Ythan Challenge was the fourth in her series of events, which began with the Baker Hughes 10K run in Aberdeen last month.
Her second race was an obstacle course in Stirling, followed soon after by a “zombie challenge” in Newburgh, which involved following clues in a test of orienteering skills, all the while being chased by people in zombie costumes.
She is far from finished and later this year she plans to take part in the Spartan Super 13k obstacle race and the Total Warrior 12k obstacle race, both in Edinburgh.
Closer to home she also intends to take part in the Banchory Beast 10km obstacle race in September, before wrapping it all up with the Glack Attack 5km obstacle and mud run at Glack Hill, near Dunecht, in October.
And in between races she is following a punishing schedule of weight lifting, running, obstacle training, outdoor fitness classes and cycling to keep at peak fitness.
She said: “I’ve been training hard for these events at the gym, in the sea at Aberdeen beach and with my outdoor fitness class, who I am running several of the challenges with.
“They’re a great bunch and it’s always fun to train with them.”
She has set herself a target of raising £1,500 and has managed to surpass the halfway mark already. To donate go to www.justgiving.com/ClottyJude
