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.

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.

I really enjoyed it and got a lot out of it that I could apply.

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.
