It was a great experience and I was full of energy and enthusiasm as we started. We had loads of fun and came second. It was a memorable day and I recommend it.

Just to say thank you for the fantastic event you organised yesterday in Wendover Woods yesterday. We both had such a great time and didn't come home completely covered in mud as we thought we would be. Hope you decide to do it again next year.

Just thought I would let you know that the NSI for your motivational speech is 93% (from 98 responses out of the 120 attendees) - that is the highest rating any speaker has yet received. Thank you again and congratulations.

Feedback from a high achievers event where the past guest speakers have been Colonel Bob Stewart and Bear Grylls.

We wanted to organise some customer events that were different from the usual eating and drinking. Extreme Energy organised a fantastic mountain biking event for us over two days in the Chiltern Hills. With a mix of trail lengths,, orienteering, and downhill thrills there was a challenge for everyone, whilst staying within safe bounds. The organisation was superb, including guiding, technical and medical back up and just general encouragement. We know that the standard of professionalism reflects back on to us as the hosts, and we were delighted with our customerís feedback. Bob Falconer CEO Gamma

Just wanted to say that your speech yesterday was excellent, I think the applause from the crowd was a good gauge of how impressed everyone was.
