It would help to have a strategy in place for how you approach each race and the relative distance, given the variety of terrain. Also keep in mind how you are likely to react to each race and the relatively short recovery time before the next race.
Kevin - I think the Tour Of Merseyside event was an immediate success last year, allowing a fantastic band of runners to take on a double marathon over a six week series - and make a stack of new friends along the way.
That was a perfect example of life beyond the marathon. It will be a fantastic occasion this year and as I said in my previous comment we have moved on from the politics of what had gone on before. We have a great portfolio that runners can be proud of.
