While on this expedition, Angelo hopes to cross not only every line of longitude, but also every line latitude as well. In order to accomplish that feat, he must not only circumnavigate the planet east to west, but also north to south. That means he'll take a somewhat traditional path around the world, before then going pole-to-pole. If he manages to complete these back-to-back circumnavigation attempts, he'll be the first person to do so.
The route that Angelo intends to follow will of course cross through all seven continents, and pass through 48 countries along the way. He also intends to row across 4 oceans and 9 seas, and cross through 6 deserts, including 5 of the world's largest. If he manages to complete Expedition 720º, he'll travel a distance of more than 115,000 km (71,457 miles) in the process. That would make it the longest human powered journey on record.
Of course, Wilkie-Page has other goals in mind beside just setting a bunch of distance records. He is hoping to raise $1 million to support the Heifer International organization, a nonprofit that is dedicated to stamping out hunger and poverty. That money will be enough to help 10,000 individuals, or 2100 families to rise out of poverty, while giving them the tools to sustain themselves indefinitely.
You can learn more about Expedition 720º at the official website, and follow Angelo when he gets underway in about a month and a half. It should certainly be an ambitious expedition to follow.
