Challenge yourself on the legendary roads used in the Clásica de San Sebastián professional race with a demanding guided road cycling experience through the Basque Country. Long climbs, coastal scenery, and iconic ascents combine to create a rewarding ride for experienced cyclists looking to test their endurance and climbing ability.
Your guide will meet you directly at your accommodation before setting off on one of the most challenging cycling experiences in the region. The route follows several of the famous climbs featured in the Clásica de San Sebastián, giving riders the opportunity to experience the same roads used by professional cyclists during one of Spain’s best-known races. Throughout the day, the route combines coastal scenery, mountain terrain, winding descents, and demanding ascents that require strong fitness and previous road cycling experience.
Among the major climbs included are Jaizkibel, Erlaitz, Murgil (Igueldo), and Aia, each offering a very different challenge. Some climbs are long and steady while others become steeper and more technical towards the summit. The ride is designed to recreate the feel of a professional race route while still maintaining a manageable pace for experienced recreational riders. Guides adapt the rhythm of the day depending on the group and weather conditions while ensuring there is enough time to enjoy the scenery and recover between major climbs.
As the ride progresses, cyclists pass through quiet Basque roads, small villages, forested mountain sections, and open coastal viewpoints overlooking the Bay of Biscay. The final sections bring together many of the climbs that often decide the outcome of the professional race, creating a memorable finish to the experience before returning directly to your accommodation.
Donostia - San Sebastián is widely recognised as one of the top cycling destinations in northern Spain thanks to its combination of mountain terrain, smooth roads, and direct access to the coastline. The surrounding Guipuzcoa region provides a huge variety of climbs within relatively short distances, making it ideal for long-format road rides with continuous elevation changes.
Many of the roads used during this experience are famous within professional cycling and regularly feature in international races. Riders can expect quiet mountain roads, traditional Basque villages, forest climbs, and dramatic sea views throughout the route. The area’s cycling culture is strong, with local riders using many of the same roads year-round for training and recreational rides.
This ride is intended for cyclists with a medium to high level of road cycling experience due to the total distance and elevation gain involved. Riders should be comfortable spending long periods in the saddle and climbing continuously throughout the day.
Suitable sporting clothing is required, along with the fitness needed to complete a demanding mountainous route. Previous experience riding road bikes on steep climbs and descents is strongly recommended to fully enjoy the experience.
Routes are carefully designed by local cyclists who know the roads, gradients, and conditions throughout the Basque Country exceptionally well. Rather than simply following standard tourist routes, the experience focuses on creating a genuine road cycling challenge inspired by professional racing while still remaining enjoyable and achievable for experienced riders.
Groups remain small with a maximum of eight riders per guide, allowing a more personalised experience and better support throughout the day. Starting directly from your accommodation also makes the ride more convenient and allows cyclists to focus entirely on the experience from the moment the day begins.
Group sizes are kept between 1 and 8 people to ensure a more personal experience and allow guides to adapt the ride to the group’s pace and ability level. Smaller groups also make it easier to move through both city routes and countryside trails comfortably.
If your group has more than 8 people, please use the “Can’t find a date or have a large group?” button above the booking form to send an enquiry. Larger private groups can often be arranged depending on guide availability and the type of ride you are looking for.
This experience is designed for riders with a medium to high level of road cycling experience due to the demanding climbs and overall distance covered during the day.
Cyclists should already feel confident riding long distances on mountainous roads and managing sustained elevation gain over several hours.
The route includes several iconic climbs used in the Clásica de San Sebastián professional race, including Jaizkibel, Erlaitz, Murgil (Igueldo), and Aia.
Each climb offers different terrain and gradients, creating a varied and rewarding challenge throughout the ride.
With 125 kilometres and around 2100 metres of climbing, this is a physically demanding route intended for committed cyclists.
Long ascents, changing gradients, and extended riding time make good fitness and previous road cycling experience important for completing the tour comfortably.
The guide will meet you directly at your accommodation in Donostia - San Sebastián to begin the experience.
Starting from your accommodation helps make the day more convenient and allows riders to avoid carrying equipment across the city before the ride.

Sporting clothes suitable for long-distance cycling are required, along with comfortable footwear or cycling shoes if bringing your own pedals and setup.
Weather in the Basque Country can change during the day, especially in mountain areas, so lightweight layers are recommended.
