It's deffo worth the extra.
I don't know about your fitness level, ability or motivation, but if it weren't for Marco and Steve (?) our guides, we'd not have ridden anywhere close to the amount we did or been as safe.
- First trip day 2, I got lost. The guide found me. It's a lot scarier in a remote Spanish mountainside with no humanity around than at a trail centre.
- Second trip, day 4, I bonked. Guide made sure I was hydrated enough to finish the ride.
- Final day. Massive puncture, was being a wally trying to fix my tyre. Guide sorted it.
- Final day, final trail, one of the hardest I've ever ridden. Without the guide's wheel to follow it's anyone's guess as to whether I'd have made it down in one piece.
Some of the trails there are pretty much zero tolerance for failure. Your safety is worth more than £130 saved. The guide's trail knowledge and assessment of your skill could mean the difference between life and death.
The guide is for much more than just showing you the way. They make sure you and your friends are safe and don't ride anything over your comfort level. You could get some maps off a random internet person and have a go. I wouldn't.
