Day four, the penultimate day of the festival, and what a day it's been.

The energy levels have been as fantastic today as they were when we kicked off on Monday and whether that's through the caffeine or sheer enthusiasm it's great to see.

I started my day today with Peter Bourke and Bertrand Chan, from CKI, and gave them a tour of the site and they were both very impressed by what they saw going on in the sprints. 

Peter also spent some time in the Hackathon this afternoon and ended up judging the competition, he told me he left amazed by some of the work he saw and people he met. 

We then had some guests on site from Anglian Water and I took Iain Fry and some of his team around the festival and showed them what was going on. They are looking to run a similar style event in the future and we're very impressed and left full of innovative ideas.

I had the pleasure of meeting Michael Roberts from Water UK today and we talked at length about the vision behind the festival and he was very complimentary and enthusiastic about what we are doing and loved being part of it. 

I also managed to squeeze an Indian head massage in, it's a hard life, and then had the pleasure of judging the teenagers bedroom of the future competition. 

The entries were all to a very high standard but the winning entry had clearly thought about the customer, the impact on the world around them and produced a fantastic end product. I was delighted to be able to hand the award over and while there I may have found a potential apprentice for the future, very exciting!

In between all of this I've managed to get into all of the sprint tents and it was clear to see how hard everyone was working to get their projects and presentations finished.

I can't wait to see them and what else the final day brings.
