i have been an on off runner for the past few years. i did my first marathon this year after training quite hard. i then had a knee operation which im now recovered from.
Im 27 and am preparing to get back into running again. i want to set myself a ridiculously tough challenge to fulfil by the time im 30 but don't know what.
Im the sort of person who will put my mind to anything until i can do it - just to prove to myself and dp!) that i can do it - i don't like giving up or failing at things!!
so i want to take this seriously and set myself a tough challenge eg - x,y, and z by the time i turn 30, or 7 marathons in 7 days, or something like that. it doesn't matter when it starts, i could give myself a year to train if i have to if its that tough, but want it to be a real challenge mentally and physically.
i want a list of suggestions so that i can pick one... your suggestions please!!!!!!
