"On a more positive note, I've used a proper toilet for the first time in 2 weeks. That was pure luxury right there. No flies. No ants. :)"

16:00 - By this point Mark was out of normal mobile signal but was able to speak to Gary and Lisa on Real Radio breakfast show through the satellite phone. Click here to catch up on the interview (update 7).
As you can tell, this was quite an emotional interview. Not only did this highlight the physical and mental torture that Mark is enduring on a daily basis but this also shared a message from the heart of someone who is benefitting from the fundraising at the Sir Bobby Robson Foundation. Ali's husband is a patient a the Sir Bobby Centre and we had the pleasure of meeting them both a short while ago. Ali has adopted the role of Mark's 'twitter mum' often sending messages of support (and strict orders!). A previous quote from Ali: "The money you are raising makes a direct difference. For me, it's having a husband and for my son, a dad, for longer". This really does help to build perspective on why Mark is prepared to endure this daily battle.
I spoke to Mark a short while after the interview when he confirmed that he had ended day 27 on 26.8 miles. The plan was to effectively use the 12 hours as rest and to allow Jason to continue to treat his feet. There are now only 4 days left with Jason as support so Mark really needs to utilise every moment.
Mark was very adamant in highlighting that, even though he is going through this physical and mental pain, he will not quit.
There is so much at stake for the two charities and that's not something he is willing to sacrifice. Donations are received every day with humbling messages of support for Mark. He will continue until he reaches his goal of £50,000. The messages of support and donations are what really spur Mark on. Please continue, it is very much appreciated.
In a nutshell, as long as Mark is able to put one foot in front of the other he will continue each day until he gets to Bondi Beach, Sydney, on Christmas Eve.
And finally, here are two great messages of support sent through to Mark today:
