Not sure if it is doable but I am raising the bar this year. I am planning to do 4 marathons this year. Coming to think of it, it does look crazy but going to give it a shot.
I am not following any particular training plan, but have set myself two cardinal principles: 1) Log 50k a week 2) Do not miss a run for two consecutive days. My take is, if I am consistent and ensure that my body / muscles learn to take the abuse on a consistent basis then I should be good.
Of course lot depends of my family / work schedule and stuff.. but I have signed up for the following marathons: 1) Auroville in February 2) Paris in April 3) Berlin in September and 4) Singapore in December.
