How a 4:16/km marathon stacks up to other distances at the same effort.
Coach's note. A 3:00:00 marathon predicts a ~18:46 5K. If your 5K PR is faster than that, you have the leg speed — focus on aerobic endurance.

To run a 3:00 marathon you need to hold 4:16/km (6:52/mi) from start to finish. At that effort you'll cross halfway in 1:30:00 and finish in 3:00:00.
Elite race data and sports science show that running even splits, or slightly faster in the second half, leads to better finish times. Starting at your goal pace, or 30 to 60 seconds slower in the first half, helps conserve glycogen and delay fatigue. For most recreational runners, sticking to even splits is usually the safest and fastest way to race.
