When the temperature outdoors is over 80, I advise no running. It can be damaging to most parts of your body. Treadmill in the gym with a/c is fine.
Admittedly, I am not a fan of road running anyway. Trail running is fine for a cardio day, but 2 days of cardio is enough for those who are already in decent shape. As we say, once you are in decent shape, 2 hrs cardio, 2+ hrs of weights, 2 hrs calisthenics.
Reminder: "Jogging" - like 4-5 mph - is slow running. It does little to nothing for cardio fitness, but it is good for maintaining endurance. We are fans of HIIT for heart fitness.
