Three participants of the UTMB are running in the hills of Chamonix. The famous peaks of the Mont Blanc range are in the background. The Ultra-Trail du Mont-Blanc (also referred to as UTMB) is a single-stage mountain ultramarathon. It takes place once a year in the Alps, across France, Italy and Switzerland. The distance is approximately 166 kilometres (103 mi), with a total elevation gain of around 9,600 m. It is widely regarded as one of the most difficult foot races in Europe. It's certainly one of the largest with over two thousand starters. The combined participation in all of the events is approaching 10 thousand runners. While the best runners complete the loop in slightly more than 20 hours, most runners take 30 to 45 hours to reach the finish line.

On Saturday 5th December 2015, Storm desmond crashed into the UK, producing the UK''s highest ever 24 hour rainfall total at 341.4mm. It flooded many towns including Keswick. This shots shows one of two railway bridges on the old Keswick railway line that were completely destroyed by the floods. It also shows a tree, now sat in the middle of the river, that used to be growing on the river bank. The force of water was such that it has scoured out huge areas of banking and realigned the river in places.'
