Marathon?

I thought about training for next years marathon to do something good for charity, but i guess this would not be good for me also training towards amateur fights, as i would lose explosive attributes due to all of the aerobic training over long mileage, maybe i should wait untill i stop boxing? anyone have any views.

It will take you about 3 months to get over it.If your fit 2 months to prepare.I only ever did 1 and the memory will last forever.Its worth it.

cheers the season will nearly be over by that point so should have the summer to get back boxing fit, thanks for the help.
