The bulk of the group will be arriving in Saint Lucia aboard the Carnival Liberty cruise vessel, on the morning of Thursday 4 February 2016.
In Saint Lucia, the runners will link up with local runners to contest distances from five kilometres up to a full marathon, on a loop route in Cul De Sac.
Saint Lucia aside, organisers are coordinating runs over the course of a week in Puerto Rico, the US Virgin Islands, Barbados, St Kitts and Sint Maarten.
During the week, “adventurers and sports enthusiasts” are taking in a trip described as “filled with unique running challenges and cultural immersion.”
Local coordination is being handled by the Ministry of Youth Development and Sports, in collaboration with the Ministry of Tourism, Heritage and Creative Industries.
The ministry will be bussing the athletes down to the venue, and partners including Paradise Springs and Peter and Company will facilitate water stops.
The run is also supported by the Saint Lucia Red Cross and the Beckwith International Leadership Development programme.
Thursday’s Pitons Peak Marathon gets underway from 9am.
