18 mile run

Another breakthrough run. 18 miles, 3:09:00, (10:30 min/mile) HR 148, weather was 85 degrees and very humid. This run really took a lot out of me. My calculators say 1800 Calories used but I only took in 600 and I felt like I was nearing a bonk at the end. Going to have to discuss this with someone to get some answers about calorie intake. Next week has a 20 mile run planned and after that I go into race-like preparation during my build period. It is possible that I will break that run into two 10 milers (morning and afternoon) and do the 20 in the build period. I will definitly take it easy tomorrow.
