I have personal responsibilities that require that the only time l have free to run is 6:15 to 7:30 am. The problem is l have responsibilities that get me to bed at sometimes 12:30 or 1am. I am able to go back to bed for another 4 hours at 8:45 am ,giving me 8 to 9 hours total of sleep. I only do this about 13 days out the month; typically 4 days at a time. Can l get by like this? I have no other choice. Typically out the 10 to 13 days a month, l have to follow this schedule. I don't have any other choice o to get my run in. For example, tonight l will go to bed at about 12:45 am, get up at 6:10am, run till about 7:30 or 7:45, then take care of what l have to till 8:30am, go back to sleep till 12 noon. Some days l can only go back to bed till 10am, but that is only 2 times a month.
