What Runners Say About Our
Bull Running Tours
★★★★★
“Highly, highly recommend if you are considering running with the bulls in Pamplona. The information was so thorough. Not only did he provide history of San Fermin but he gave a lot of suggestions on how to run, where to be, what to avoid, how to be safe and not to do stupid things. My adult sons felt much better about the run after speaking with Dennis. He also stuck around to make sure everyone’s questions were answered. It was well worth the time we spent to get all this info. And as a mom, it put me at ease too.”

The tips he provided were invaluable for the experience ahead. After his tour I felt a lot better doing Encierro for the first time and didn’t hesitate to do it again the next day. He has a healthy respect for the tradition and he himself is a great guy.

Host was very communicative on planning our meetup, making sure all were comfortable finding it. The tour was very thorough, Dennis emphasized we can stay as long as we need to answer additional questions. Because he is a current runner and not just a historian, he was able to speak with great detail on what to expect “this year” or recent changes. I feel way more comfortable for my run, great energy in this group and it’s clear that Dennis is passionate about the subject.

Great information if you are planning or considering to run with the bulls. I had no idea what to expect when running before this tour and ended up running on the final day of 2023 and made it through unscathed.

I highly recommend this guide with Dennis. Not only was it well informed, but it also provided a lot of skills and techniques that make you feel a lot more confident on the run. I recommend this for anyone doing the run or for general information as well.

Dennis is very knowledgeable about the run, offering some historical information along with the best ways to approach the run and things to avoid. He is patient and quite engaging. We saw him before and after several runs and he always stopped and spoke with us. Having completed his walk through, I think it is a must from a knowledge and safety standpoint.

If you are considering running with the bulls in Pamplona, I highly recommend Dennis’ advice and coaching. Dennis is experienced, caring and personable. His tips proved to be accurate, insightful, and geared toward maximizing the experience while minimizing the risk. Dennis is a celebrity in Pamplona, and you will continue to see him often throughout the Festival. He’s a great guy, and knows what he’s talking about!

Dennis knows the history and culture, the bulls, the course, and how to run Pamplona. I'll be more confident (and safer) when I run. Highly, unreservedly recommended.

Highly recommend booking this experience for anyone who is on the fence about running during the festival. Dennis was very informative, answered all questions we had and gave out some great tips for people who were running for the first time.

I saw Dennis on YouTube and watched a documentary of his called Chasing Red. AirBnb suggested a tour for my Pamplona visit and to my surprise it was the American bull running expert Dennis. Got a lot of questions answered; and Dennis was very understanding and easy to get along with. Needless to say I felt confident going into the run; and survived to leave this review - thanks to Dennis!

Because the experience got off to rocky start outside of Dennis’s control because of crowds there was some confusion and dismay. Dennis quickly won me over and highly recommend him. Experience was 5 star for value and knowledge gained from it.

Dennis was terrific. Super informative and patient with all of our questions. He was friendly and warm and was great with answering questions about the area and the bull run before the tour through the messaging app. I definitely recommend it if you are planning to run.

The advice I value most is from someone who has successfully done it. So getting tips from one of someone as knowledgeable as Dennis is as good as it gets. This is a must do experience for any first time runner.

Insider knowledge and invaluable information for those who plan to run the famed streets of Pamplona with the revered Toro Bravo bulls, as well as a deep history and understanding of the San Fermin festival for both runners and spectators.

Dennis is an expert! Do take his advise. The colosseum is really dangerous but ride the butt of the last bull in, the entrance is really dangerous as Dennis said.

Wow! if you go to Pamplona for the first time for San Fermin you need to contact Dennis. He gave us a detailed tour on what to do, what to expect, where to go.. how to run.. everything... I think we would have been pretty lost without him. He also has a great group of people so is a good way to make new friends.

Dennis is solid gold. Not only do you get a detailed description of the physical terrain of the running route—which is extremely important—you gain great insight into the culture of the bulls, the encierro, and the San Fermin Festival. Cannot recommend the tour or Dennis's expertise enough. As they say in Navarra: Viva! Gora!

Dennis could be straight from The Sun Also Rises- an accomplished veteran and intrepid artist who guides the magic of Pamplona’s history and culture to life in a uniquely personalized and utterly modern way.

Dennis is a highly professional, warm and engaging expert on all things Pamplona Fiesta. Where else can you get someone who has literally made a documentary about bull running to show you the ropes? Throughout my experience, Dennis made terrific recommendations.

Dennis and Anthony are masters of this run. They know all the ins and out. They also take the local culture into consideration and they are focused on fun and safety. If you're a first time runner, you shouldn't step foot on that course without taking this tour.
