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 customer’s feedback. Bob Falconer CEO Gamma

QinetiQ are pleased to have used XNRG for their team building as XNRG have the right values when it comes to teamwork and were always there to help – the QinetiQ team knew XNRG would not let anyone down. QinetiQ chose XNRG on the basis of: 1) XNRG are inclusive and every competitor is treated the same be it the fastest or the slowest person; 2) XNRG clearly have a love of the challenge and want people to succeed and will do everything they reasonably can to make it happen – people having fun and succeeding are in the XNRG DNA; For what we did XNRG represented very good value for money.

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.
