Use the commute to your run location to warm up. Ideally no more than 20mins light jog. This should all feel really easy, so your muscles can warm up properly before the actual session.
If you feel like you want to add some speed, do so. But if you feel like doing a rather slow run that’s totally fine as well. The key is to really listen to your body and give it what it needs. No need to push through a certain mileage or pace if you really don’t feel like it. Believe me, your next season will be back sooner than you expect and by then you’ll be glad that you’ve taken some time to reset your mind and recharge fully!
