Notes
Hard going on a warm day (29 degrees and humid). Feeling the pace by 4km and had difficulty adjusting from 5km pace to a 10km pace. Found it hard going all the time after that - to 6km, more so to 7km, after that felt like the return journey and just tried to get through without slowing too much.
Not one of my better days, rather hard going, but another step on the path towards good times later in the year.
Took beetroot juice the night before (then used mouthwash so probably no benefit) and used Newtons, which were ok but did not feel particularly quick.
