Advise on watch stats. Ran my 1st half at Chester today failing to get a sub2 (2:02:30). Fairly new to running at 48 & diagnosed with MS last autumn. When i look at my running stats on my watch it shows 80% aerobic endurance, but on heart rate it shows 45% anerobic power at 170+ heart rate.

Is that telling me i was close to my limit even at the slow pace or showing i still plenty in the tank???
