One of my favourite events to attend locally is the Bath Half Marathon. 2017's was the best-attended ever, with so many taking part that the organisers ran out of medals for the finishers! It provides a great opportunity for photographers, as long as you follow two golden rules:
Both the family fun run (above) and the full half marathon attract runners working on behalf of a range of good causes such as Marie Curie (below).
Many photographers stay for the whole event, but for me, the best pictures are in the early stages, with runners still in good spirits (below) and expectations high!
Will definitely be back in 2018!
