Athletes will be digging out their running shoes in preparation for its return to Sierra Leone in June.
Amid searing temperatures, runners wind through tropical jungle and traditional villages while raising money for global charity Street Child which aims to get children back into education.
The racing adventure begins in Makeni at dawn, finishing back at Wusum stadium to a hand-carved medal and a cold beer.
Athletes then have the option to take a triumphant flight home or continue their journey to one of Sierra Leone’s tropical beaches.
CEO and founder Tom Dannatt said: “It’s brilliant to see the return of the Sierra Leone Marathon next year. It is a very special event for the whole of the Street Child team and a jewel in the crown of our events calendar.
“See you all on the course in Makeni!”
The last event in 2019 saw more than 100 runners tackle the trail in 30C-plus temperatures as veterans lined up alongside novices.
Participants also have the chance to attend workshops and see the impact of Street Child’s fundraising when exploring Northern Sierra Leone where its rural and urban projects take place.
Runners World magazine dubbed the event “the craziest and most worthwhile marathon”.
There is something for all running abilities with a full and half marathon plus a 10k or 5k option through the beautiful countryside.
Katherine Barr, Sierra Leone Marathon event lead, said: "I'm so excited to see the return of the Sierra Leone Marathon in 2022.
“It is a hugely memorable and important event for Street Child as Sierra Leone is where it all began back in 2008.
"We really missed it from our calendar of events last year, but now we are back and ready to get started."
