That's great news Alan, never mind about the time just running the whole thing is enough at this stage!
I have toyed with the idea of marathon distance but not sure I want to cope with the damage it will do at this time with summer on the way. I entered a 16.45 mile virtual race (26.5km, like a metric marathon) which allowed the whole of February to run the usual course starting from any intermediate point, or indeed create your own course as long as elevation was sufficient. I had 3 tries, hoping to average 6 min/km for 2h 39min. I had run a half in 2:04 in January as a test. First attempt was a misty day and I got lost at 18k, repeated a hilly section then headed down to sanctuary having completed 30k - 2h 44 for the race distance. This was 2 days after my Pfizer jab. Tried again 11 days later, proper course, 2h 37m. Bought a pair of Brooks Hyperion Tempo shoes, tried again ten days later on a different but equivalent course, 2h 32m. Won the 70+ category. Only one in the category, mind, but only one 55+ yr old was faster. Also carried on to 30k to meet the virtual County Gold standard (3 hours) by the skin of my teeth... February was a big month for me, March focused on speed over 10k, 7, 8, 10 miles and finally a 1h 54m half marathon to complete 9 Gold standard runs.
Things don't last of course, right leg is starting to complain a bit now (4 years since THR) but I have had a great few months just concentrating on running. Chance of a Diamond mile if I can get 6:56!
Good luck going forwards with your racing!
