Swelling in your hands during a marathon is common.  There a few factors that can cause this; weather and electrolyte imbalance.  Warm weather, cold weather and altitude can cause your hands to swell.  When running your marathon, your are sweating a lot and you are not replacing your electrolytes.  Electrolytes are in the salts in your bloodstream.  Once you start sweating, you lose salt.  Try a sports drink after your marathons to help replace your missing electrolytes.
