However his aim of hitting his 500,000km target is now on hold after his bike was stolen while he took a nap in the Mexican city of Veracruz.

According to Mexico News Daily, Simoes stopped for a rest in the city on the eastern Mexican coast, awaken from his nap to find his bike gone together with all of his possessions and mementoes from his journey.

The 53-year-old says that he will stay in Veracruz for a short period in the hope that his bicycle and possessions might be returned.
