Fat Turkey, Well! It goes something like this....I was aiming for a 3.30 marathon, got to 13 miles, RW pacers behind me, then in front of me, heart rate too high, slowed it down, made 3.42 but enjoyed the whole race..WHAT A CRACKING RUN! Next year will be the 3.30!..If you can't hit your target time, then enjoy, that's my view!
