You can do anything when you hit 18 I was downcast after Doncaster , but my longest run so far -- in a respectable time -- has put a spring in my step ( and an ache in the rest of me ) . In this mood , I could run all the way to London and still get round the marathon course . I 'm pleased to say that this week things have improved . I managed to run 18 miles on Saturday and that was quite comfortable . It 's cheered me up to know that the Doncaster half-marathon last week was such a disaster because I was ill , not because I was unfit . That one long run has given my confidence a boost and I 'm convinced I 'll now survive London . It was n't particularly fast -- three hours 21 minutes to be exact -- but at least I know I can do it . Doncaster put some doubt in my mind but I 've bounced back -- in fact it 's spurred me on . I 'm looking forward to the next few weeks of training and I 'm hoping to speed up a bit . I do n't think I 'll be challenging Paula Radcliffe but hopefully I might break five hours . That 's my goal and now I 'm back to my usual cheery self I 'm determined to do it .
