Having done a few of these before, I am very away of how the structured marathon training changes you physically over time. During the summer I have put on a little weight as I had to ease up from running because of a tendon injury. I forgot to adjust the diet and just kept eating, not so clever. However because of this I am expecting the training to have a very noticeable effect. I will save you from the usual before and after photos (unless someone sponsors me loads) and just give core data as a benchmark.

Current Fitness Level 29th Oct 2017 – mostly taken from Garmin 235 data.

Average Resting Heart Rate (over 7 days): 62 bpm

Weight: 208.6 lbs (Nov 2016 I was 189, that’s the effect of not running and continuing to eat the same)

Waist size: 38 1/2 inches

10k Time: 51(ish) as I was running with dog (PB was this year 44.41 on 26th Feb 2017)

VO2 Max: 46 (Feb this year I have been at 52, so quite a bit of a drop in fitness)

Let’s see what happens over the next 5 1/2 months.
