<human>: Give me a shortened version of the text

So I've been running practically 5-6 days a week since february, up until June. After June, college has gotten in the way. I have only been able to get enough energy, for a run every two days, and noticed that my stamina has dwindled severely since starting college. Normally I would have enough energy to push through 2-3 miles, but as of now my focus has been primarily  on beating my mile times instead of long distance. I am starting to realize however that if I am to go long distances, I shouldn't be trying to go all out on the first mile. What tips would you suggest, to help me maintain a constant but comfortable pace and complete 2-3 miles comfortably? Should I have a regimen of focusing on pacing and distance, rather than speedy 1 miles?
