I was up before sunrise this morning to get as many miles in before it started to heat up. In addition to comfort, the next water source was 19 miles away and hiked by in the cooler temps minimizes the amount of water that needs to be carried.
I have an extra early departure planned as the next water is 32 miles away. My plan is to head out around 4:30am get 20mi done before noon. Take a long siesta and do the last 12 after the sun drops a little lower (3:30?). There may be a water cache along the way some local trail angels maintain but you can’t really plan on it.
