I am training for my first marathon and have progressively over the last few weeks gone from 9>13>15>18>20>22.
A little background:
I had a good base a year ago but then just stopped running. So have built up to this milesage over the last 3 months (can check my log). I employ the low-heart rate training techinique and am also now at altitude (~ 7000 feet in Flagstaff, AZ).
My problem was that this week when I attempted 22 miles I had a lot of pain/cramping in my calves at about mile 19.5.
I took electroylte tabs about every hour, ate clif gel at 1:20 & 2:40, and consumed about 1.75 L of water during the time (nearly 4 hours before crash).
Would love some advice please as I am to run NYC in November and don't want to crash. Too little water? Too fast increase?
Thanks!
