I have only trained for and ran one marathon so far. However, almost every run I did from 2 – 20 miles was at an 8:00 minute per mile pace. That is almost the exact pace I held for the entire marathon start to finish. I did no strides, hills, repeats or anything else – just a building phase at the same pace for four months that tappered to race day. The race was great – I had virtually no problems. Marathon training pace helped me tremendously for my first (and only) ((so far)) marathon.
