Rob Connelly, assistant head at Archbishop Sancroft High School in Harleston, has been a spectator at the London Marathon on numerous occasions - but this year he will be out on the course running it for the first time.
Mr Connelly told the Diss Express: “Training has been going very well. I have been training for four weeks.
“I only found out four weeks ago that I had secured a place, so I have been fairly late in training, but I am up to 15 miles a day as we speak - I am on schedule.”
He is raising money for CLIC Sargent, a children’s cancer charity. He hopes to raise £2,000. With online and offline donations, plus a non-uniform day held at the school before half term, Mr Connelly is up to £1,200.
He said he is very aware of the work the charity does, as it currently supports one of the students at the school.
“They (CLIC Sargent) support young children who have cancer or leukaemia and I have been privileged to have worked with families who have benefitted from their support.
“The school community has been really getting behind me, which is great.”
