A good mix of runs for half-marathon training. Two or three aerobic runs, 4--6 miles long, run entirely aerobically. One tempo run: 6--10 miles long, run 50% aerobically, 50% harder-than-race-heart-rate. One day of speed work (800-meter repeats, or a quarter-mile hill workout), every other week, usually about 5--6 miles total. One long run, approximately 80% done aerobically, with the last ~20% at "race heart rate". One day of cross-training (a 30--45-minute bike ride). Check out the run!
