Detailed Information

  • Your trip will be led by experienced Discover Adventure leaders and support crew. Our leaders are selected for their knowledge and experience, friendliness and approachability, sense of humour and ability to safely and effectively deal with any situation that arises; they are also trained in first aid. You are in very safe hands with a Discover Adventure leader. The crew will have mobile phones and/or radios where appropriate, medical kit and other safety apparatus where necessary, as well as vehicle support.

  • An expedition doctor or medic accompanies the group (dependent on group size.) Their role is to look after the well-being of the whole group and deal with any incidents. They help the leaders to ensure the trip runs smoothly, and encourage you when things get tough. The total number of crew looking after you will depend on the final size of your group, but at Discover Adventure we pride ourselves on our high leader: participant ratio and believe it leads to greater trip enjoyment as well as excellent trip safety.

  • Your safety, and that of the rest of the group, is our highest priority. Our trips are designed and planned with safety in mind. Your crew will be equipped with communication devices (eg phones, radios and/or emergency satellite phones), medical kit and other safety apparatus appropriate to the destination. Our leaders always have access to our 24-hour emergency UK back-up. They are responsible for safety on the trip, and will make any changes to the itinerary they deem necessary, should local conditions dictate. Pre-trip administration - such as medical questionnaires and travel insurance as appropriate - is all done with your safety in mind.

Preparing for the Challenge

  • We plan our trips around the optimal weather conditions, but could still be exposed to bad weather at any time. It is vital you are prepared for all conditions. We provide you with a detailed packing kit-list on registration, as well as details on useful discounts you are entitled to as a Discover Adventure customer. We are always available if you need advice.

  • This is designed to be a challenge, and it is vital that you train sufficiently for it. We will supply you with a thorough training guide once you have registered. Training is all part of the preparation: inadequate training will impact on your enjoyment of the trip, and your chances of completing it. We expect all participants to train hard in advance, but we respect everyone’s limits and do not expect everyone to maintain the same pace. If you have concerns about your fitness or if you have reduced mobility please do contact us for a confidential chat about whether this challenge is appropriate for you.

It is very hard to describe just how wonderful this trip was me. The sense of achievement crossing the Pyrenees is something I will never forget. The fun, the laughs, the exhilaration, the sore bottom are all things I hope to never forget too (well maybe the bottom

part). Can't thank you enough for making a middle-aged mother of three feel like she can conquer the world. I have had the most wonderful time away with DA, the crew were fabulous, the route was breathtaking, the accommodations were comfortable (and in some instances luxurious) the food was ample and delicious (especially the celebration meal at the end) and the overall care and attention to detail by discover adventure was absolutely perfect.  Thank you to everybody involved it truly was the most incredible trip which has made a novice cyclist quite obsessed with her bike! Huge thanks to all at Discover Adventure.
