yes id say too..if you feel ok below the neck then chill it and run slow if you dont like missing races, but stop if you feel bad at all..... below the neck,,chest etc...a no no id say.
i thought this race was not really so good, having done it now.... nice medal..and thank goodness,nice weather, that could have made it a real bad day for me.....the route is boring and atmosphere very flat....and not 1 portaloo on the whole course for full marathon.
