How is best to deal with blisters when running a marathon?

I am running the NYC Marathon next month. Its my first marathon and my training is now getting pretty intense. I have developed a re-occuring blister on my 2nd toe as it rubs against the middle one when I run. What is the best way to firstly let this heal quickly and secondly to stop it irritating me on the race... show more I am running the NYC Marathon next month.
