I have prepared a training programme based on 3 runs a week with an option for a 4th run.
This programme is aimed at busy folk, who work, maybe have children to look after and just do not have the time to run 4-6 times a week. Ideal for first timers, or if your first marathon was a painful experience then this could be for you.
This is the same programme I used to coach a group of girls doing their first marathon at Dublin. They all ran well, nobody hit the 'wall' and their finishing times were from 3.44 to 5.27.
Email me if you'd like a copy of the programme
