1) Virgin Gorda Yacht Club: ran from there up to the Baths and beyond. No sidewalks so you have to be careful of traffic
2) Trellis Bay: ran from dock past airport and off Beef Island onto Tortola. Again careful of traffic
3) Bitter End Yacht Club: trails over to and through Biras Creek Resort.

Good luck with training and like one poster stated, sometimes it good to have some time off from running.
