An Edinburgh dad will participate in the city's marathon in order to raise funds for life-saving treatment for a young boy with a stage four brain tumour - a year to the day his own son was diagnosed with the same condition.
Martin Bryce will take on the gruelling 26-mile challenge and has recalled the "horrific" day he was told that is then eight-year-old son, Leo, had a pea-sized lump on his skull that was cancerous.
Martin is running the Edinburgh marathon for eight-year-old Rudi Abbott, after hearing the heartbreaking news that there was no more the NHS could do for him.
