Did one on Monday that as previously mentioned that ended up becoming an unplanned PB. Been in active recovery, concentrating on form improvements rather than pace, since then. Will take my own advice and have a rest day today, then an attempt on Friday, leaving me Sunday for a last ditch attempt if it does not pan out.
It is hard working out what pace to go for, I know I could improve a bit but the closest nice round number (8000m) is too far. Maybe I'll give 7,905m a go (that would put me into the 90th percentile for my age group, at 1:53.8). Still quite a stretch. If I miss, perhaps a 1:55 pace at the final attempt.
Of course, my plan will probably turn into fly and die as usual
