After realising his dream of running at least a half marathon on all seven continents before his 70th birthday, Doug Richards travels to new remote locations to up his lifetime total to 24,902 miles, the equivalent of the circumference of the Earth's equator. Having discovered running late in life, Doug's journey took him from an initial one-mile run to completing long races across deserts, mountains, jungles, snow and ice. In Once Around the Planet, he shares his latest adventures, contending with a pandemic and recurring anxiety as he returns to the marathon distance in Venice, runs among ancient Moai statues on Easter Island, across volcanic rim trails and hot springs in the Azores, lava formations in the Akamas peninsula of Cyprus and ventures into the mysterious confines of the Bermuda Triangle. More than just a book for runners, Once Around the Planet gives candid insight into Doug's battles with anxiety and depression, the inevitable decline in performance as he enters his 70s and the key role running can play in good mental health.

Doug Richards, a retired medical scientist, is the author of Running Hot & Cold and Can We Run With You, Grandfather?, two books that trace his running journey from a run of a single mile to completing at least a half marathon on all seven continents. In 2022, Doug was named as 'Running Adventurer of the Year (UK)' in the Fitness and Nutrition Awards of Global Health & Pharma.
