I'm not aware of any T1's who've completed the Bob Graham.....could be a first out there for you!! If there is then I'd love to read their story.
Harry Seacombe I believe is or was type 1 I think he's past away famous for being one of the Goons and Sunday night's tv think it was songs of praise Sent from the Diabetes Forum App
I think I may have seen this when I was thinking of doing a Bob Graham in one of my moments of separation from reality.
