Blog Kate Knight At this year’s London Marathon, 27 runners will be raising vital funds for United Response. One of these runners, the unstoppable Kate Knight, a healthcare assistant from Chipstead, will be running her 13th marathon for us. Here, she talks training, stamina and what motivates her.I am feeling very confident about my next marathon, though this will not be the first that I have run this year. The last one I took part in was in Nassau in the Bahamas, and my husband Jim and I both did this one together. It was great fun as we had extra support from family - and the Bahamas is a great place to go for a recovery holiday afterwards!I was feeling very pleased to have completed the run in Nassau as I had a severe chest infection all over Christmas and New Year, which I had only just recovered from, as well as an operation on a torn meniscus back in October. Even with the heat, I was feeling good that I had made it round the course in seven hours. My stamina kept me going, particularly back in September when I managed to complete the Loch Ness Marathon with a torn meniscus in the left knee. Lucky number 13 London will, in effect, be my 41st marathon in total, as I am also looking forward to running the Brighton Marathon for another charity on 12 April, which will be my 40th marathon. London is also my 13th year fundraising for United Response.Although we have done other marathons together, this will be the first London Marathon that Jim and I are doing together, which we wanted to do as he has supported me for the past 12 years, and has great admiration for United Response. Overall, we can both support each other with the running, and at the same time maintain our fitness goals in life. Why I chose United Response Family history was the choice for United Response originally, as my brother-in-law used to run the London Marathon for a similar charity. He is the same age as me and has learning difficulties, and he and other family members have always supported me in raising money for the charity. Jim has, of course, been especially supportive and, while this is his first year in London, we hope we will both be running for United Response for many more years to come.To date, we have done six half-marathons in six weeks, some of which we have done together. Despite having surgery in the run-up to last year's marathon, this has not hindered my confidence; in fact, this has made me even more determined to rise to the challenge! Using my stamina and mind over matter to overcome difficulties in this way has been a great asset.Kate Knight was talking to Gemma Taylor, media assistant.Find out more about the London Marathon Or, to join our cheering station on the day, you can contact Sarah from the United Response fundraising team on 0208 879 4987 or by email at firstname.lastname@example.org.
