The starter's gun might not be the only thing going off with a bang at a new marathon in Chile this year. Following his world record of running seven marathons in under five days, Richard Donovan has created the Volcano Marathon on 14 November, taking participants past - you guessed it - an active volcano.
The race begins in the Tropic of Capricorn in Chile next to Lascar - one of the most active volcanoes in the world - continuing through the Atacama desert - the driest desert in the world. Runners will face altitudes of 4,300m (14,100ft) and temperatures ranging from 0C to 40C. As well as the marathon, there will be training runs and visits to Sal Mountain Range, Valley of the Moon and a chance to acclimatise at San Pedro, which lies at 7,900 feet.
Richard, a former economist, knows it's a calculated risk: "There is a constant gas cloud around Lascar, and they run past ten other volcanoes, which makes it that bit more exciting. You find out a lot about yourself running in those conditions."
Anyone can enter the race though it is limited to 30 places. For more information, visit the event website.
