Based on my current (not so great) fitness level, I defined three different training intensities, which I distinguish by pace:
Fast: < 5:00 min/km
Moderate: 5:00 – 5:50 min/km
Slow: > 5:50 min/km
The distance I plan to cover per run in each intensity group is noted under 'Plan'. The distance I've actually covered is given in 'Run'. Each week includes at least one long run (> 15 km), for which I don't define a pace, I rather let the legs call the shots. Also, I add interval runs to 'fast' or 'moderate' runs, depending on the overall pace, without specifying them any further.
