There's no doubt it's tough but also fun! Last year the guidance was to add 40% to your marathon time as a guide - I managed to add 55% .... But that was on the "short" course!
Dr Rob .... I "ran" last year and managed to get the the half in 3 hours and finished in 6:10 ..... seems tight to squeeze in another 3 miles in 30 mins to duck under the 3:30 cutoff [which I fully agree with for everyones sake] ....... do I need to readjust my goals?!
