The Greenwich Meridian
May 2026
A unique ride south from Greenwich in London following as closely as possible the Greenwich Meridian to the Spanish coast between Barcelona and Valencia.
For centuries there were various Prime Meridians in use but eventually the Greenwich one was chosen for universal worldwide adoption. The Royal Observatory in Greenwich describes a meridian as 'an imaginary line running north to south that is used as a reference line for astronomical observations. By noting the exact time each star crosses the meridian, it's possible to build up an accurate map of the sky. Meridian lines also help to measure distances and plot locations here on Earth by offering a way to determine longitude.' (Source: Royal Museums Greenwich).
Obviously very few roads were built exactly on the line but we are generally no more than 5km from it and often within 1km. The major exceptions are the two natural barriers between Greenwich and Castellon - the English Channel and Pyrenees - where we have to go off course before rejoining as soon as possible after. This will be a challenging tour with the Channel crossed by ferry but the Pyrenees by bike over the Soulor / Aubisque and Portalet, leading to the large open spaces of Spain. Generally the days are in France are shorter before Spain which has further gaps between hotels so the last four days are unavoidably longer distances, but some really fantastic countryside to enjoy.
The hilliness of each day is measured by the CQ figure (an explanation of how this works is on our FAQ page).
