The Tamara Coast to Coast Way is an extraordinary 87 mile journey of discovery along the border of Devon and Cornwall. The route traverses the majestic Tamar Valley, tracing its course from the vibrant city of Plymouth to the very source of the River Tamar.

The 42-mile Nabesna Road offers tremendous views to rival any road system in Alaska. The Wrangell, Mentasta, and Nutzotin Mountains create a majestic panorama, characterized by some of the highest mountains in North America. Nabesna Road provides access to the north side of Alaska’s largest national park, the Wrangell-St Elias National Park and Preserve. Nabesna Road wasn’t built to access the park. In fact, it was constructed in 1933, nearly 50 years before Wrangell-St. Elias was established. The purpose: to get supplies in to Nabesna gold mine, and ore out to the Port of Valdez.

This is a hot and sweaty perimeter run on the Caribbean island of Barbados. The west coast is plagued by traffic and pot holes with very few sidewalks. And the East coast is a roller coaster of hills, and blind corners. If attempting, probably best to do it at night, as it's about 2 degrees cooler and you can see traffic better. But then you do have to deal with stray dogs.
