ok so yesterday I raced 5hrs at altitude in the heat.  I drank about 6 liters, maybe 6.5.  I did not get dehydrated and still had running legs at the end. as for electrolytes : at hours 2 and 3, I took 500mg sodium + 2 Sportleg capsules( magnesium + lactate).  after a bit my belly got bloated. it was not uncomfortable exactly, but I figured it was too much sodium.  I did not take any more capsules during the race. my belly went back to normal.  I was also drinking 500ml Tailwind in addition to the 500ml of water every hour.  I think next race I will take only 500mg of sodium per hour.  I think tailwind might be 350mg, so 850 was too much.  as a side note, often in heat race my fingers get puffy.  I had no puffiness yesterday, so I was close to get hydration/electrolytes dialed
