The race was quite unique as it is only run every 10 years and it takes place on the cycleways that network the town , these are undulating to say the least . The support was good in terms of marshalls , water stations and free energy gels ! I ran steady 8.30 min miles right up to 20miles and then eased up in case i had a problem but never did, even sprinting the last 400 mts , coming home in 3.51.18, which is a p.b for me by 17 mins and a long held ambition to run under 4hrs for the marathon now achieved .
