Hi, I’m Kat and I’m a challenge events fundraiser at Great Ormond Street Hospital Children’s Charity.

There are over 1000 of you taking part in one of our amazing autumn half marathons this year and part of my job is supporting you, so I’ve signed up for the Robin Hood Half Marathon at the end of September (green tights optional) so we can share the ups and downs of our training over the next three-four months.

Twelve children from across the UK, including Jack, a Great Ormond Street Hospital (GOSH) patient, took part in the Xtreme Everest expedition recently, which aimed to help clinicians better understand how to treat critically ill children.

Laura and Katie have made it and finished the London Marathon – despite their injuries. They have a final message for all Great Ormond Street Hospital Children’s Charity runners.

David Rolph took part in the Virgin London Marathon yesterday, running for Great Ormond Street Hospital Children’s Charity. Before the marathon he told us about his training and why he was taking on such a big challenge.

Wow, how did this happen? The marathon is a matter of days away, and I feel entirely unprepared. Admittedly this is mainly because I have not been sure if I am going to be able to take part or not. So it is crunch time, and I need to make a decision.

This has been a difficult week. After a great week of running and my final 21 mile long run (which wasn’t fun, but reassured me that I might actually make it round 26 miles), I feel like I’ve gone backwards in the last week.

So last time I posted a blog I’d just been to physio with an injury, and I am gutted to say that since then not a lot has happened – I still haven’t run. My ankle is still quite sore, and I have had another couple of sessions with my physio. He had suspicions it may be a stress fracture, but this is unlikely. Instead he thinks it much more probable that it is peroneal tendonitis. So I am prescribed with icing, immobilisation, rest, and stretching.

Our marathon blogger Katie is on holiday, but took a moment to record a video blog for us telling us how the final weeks of preparation are going for her marathon.

Before sports therapy Katie and I have had a very good run in (excuse the pun), so I guess it was inevitable that at some point one of us would get a niggle that would turn in to something worse.

We’re really hitting the long runs now, and it’s starting to hurt! I had a bad week last week – my legs felt tired and my long 16.5mile run was painful by the end. I finished that run wondering how I will ever make my body carry me another 10 miles beyond that and starting to feel the fear about the marathon. I’m listening to advice and taking today off to carry on recovering. I really hate the idea of missing a run and the idea of not running makes me feel quite nervous at this point. I have to be sensible, and realise that it’s still a long time till the marathon, and a few miles today are not going to make any difference overall.
