Jez, hope things are going well for you.
Update on my situation is that I had a long discussion with my cardiologist who considered my plan of keeping pulse at 140 eminently sensible and was pleased I had been able to cut out competitive racing.
So it was with much pleasure that I took part in a race that i created in 1991 and is now in the able hands of another enthusiast who keeps the race alive. Last time I did it competitively in 2015, I completed it in 1hr 15. This time, sticking to my 140 max pulse I bimbled round in 1hr 30. Not too shabby at all and it was very enjoyable. I was dropped back into a gaggle of lady racers and what a difference! Whereas us blokes would have been silently grinding and sweating our way around, the ladies chatted about all and sundry!😂
And then, because a large part of the fast field went wrong I came home in 17th place!!😂😂 you couldn't make it up!
