Now into its 15th year, the run will take place in Saint Vincent and the Grenadines and will see participants run, kayak and finally hike the 50-mile route to the top of La Soufriere, the island’s highest peak and only active volcano.
The runners are aiming to raise £100,000 for the Milton Cato Memorial Hospital and other healthcare facilities catering for babies and children living with cancer.
"The money raised by this year’s participants will fund emergency paediatric healthcare and make a real difference to people living in Saint Vincent and the Grenadines,” said Hays Travel owner Dame Irene Hays.
