When I was preparing for the 1972 Games in Munich, I was living at the north end of Belfast and I had to travel, with my shot put and starting blocks in hand, on a bus all the way to the other side of the city. There would often be bombs going off but I didn't know any other life; I just got on with it.
As the Munich Games got closer, however, I was fortunate enough to be able to leave Northern Ireland and, supported by the Churchill Fellowship, train for six weeks in America. It took me away from the Troubles and to a completely new environment and climate.
So I knew I had to do something special and I really think my time in the sport – I was the most experienced athlete in my competition at 33 – paid off for me. The competition was split in two halves. I managed to achieve personal bests in the first three events – the 100m hurdles, the high jump and shot put. But I knew Heide's strongest events were the final two: the 200m and the long jump.
Despite the pressure of the events, it was the waiting around that was the worst thing for me. The break in the afternoon was awful, all I could think to do was to go back to the Olympic Village. It was only between noon and 6pm but it felt like I was there a year.
I had a cushion of something like 100 points going into the penultimate event and I ended up with a fairly average long jump. Heide then leapt 6.83m – one centimetre short of her world record. I knew then that the only way I could get Gold was to run a personal best in the sprint.
We flew out of the blocks and Heide finished 10 metres ahead of me. But the pentathlon is not about positions, it's about points. And we had to wait anxiously while the computer churned out the results.
