We recognize that the long run is only one piece of marathon training. However, one of the most common questions we hear as running coaches is: how long should you run before a marathon? Should you follow the commonly cited rule that you should never run longer than three hours in training?
We re-recorded our first ever episode for an updated discussion (with better audio quality!). We dive into the science of marathon long run length, as well as provide some practical recommendations. 
Before all that, we answer a listener question about reflective gear recommendations. 
Our reflective gear recommendations include (with affiliate links):
Petzel Ikocore Headlamp 
Amphipod Xingelt Reflective Vest
Nathan Streak Reflective Vest
