Birthday ride should be done on your birthday--Thats why it should correctly be called-"Riding your age" But riding your age is still a misnomer. What Age? Actual age- The age you feel or the way you act? Probably why so many of us are happy with a 12 mile ride.
But have to agree- Good ride at a good speed- but only a ride your age for 53.
So have you done your 54 age ride yet.It's been six months since you rode your 53 age one
And on that speed thing- I can't remember the last time I broke 16mph for a metric.
