Getting older doesn't mean you can't ever beat any of your old PRs. I'm 61 and have set 607 new PRs so far in 2022. Use those old records to keep yourself motivated. 

Good on you, Chris, but as far as I am concerned let's say that this year I had medical issues that are making beating old PRs look like a miracle. 

But if I ever will break one I'll let you know.  😀

Thought about you Chris yesterday when I was struggling to try to keep up a decent rhythm. Ended up about 12 minutes above my 45 minutes PR on that particular segment. 

I spent 3 years dealing with some pretty serious health issues between 2019 and 2021. I rode quite a bit during these years, but I was not able to push myself as hard as I wanted to. I finally managed to get myself healthy again in 2022, and I've had one of my best years ever on the bike. I did a lot of racing this year, and beat a whole bunch of guys half my age. Keep pushing yourself!

I want to reset my PRs too. Last september I had a nasty crash. Broke 5 vertebrae, 4 ribs & my pelvis. I have not been cleared by the doctor to ride outdoors yet. But when I restart cycling outdoors,  my old PRs will be obsolete and of no use to measure my progression

Thank you Christophe to back my request.

And I hope you'll be back on wheels pretty soon, your crash sounds like it was pretty nasty indeed. 

I sure hope someone can provide an answer. Injuries and age can make our old PRs obsolete, especially for those of us who are older.

You tell me. By the time I'll restart cycling I'll be 63

As we age our maximum heartrate invariably decreases.  The formula is (220 - Age in years). Although regular exercise can keep our max heartrate above average, it is still going to decline. At 61, your theoretical max is 159. With a lot of training, yours may be say, 170. Someone who is 72 has a theoretical max of 148.  He would go anaerobic at about 126,  A maximum sustainable HR of 126 will seriously impair your ability to set new PRs.

Thank you for endorsing my request. 

The 220-age formula is worthless. I'm 61 and my Max HR is 185. I did a 2 hour race a few months ago and was able to hold a sustained effort at 160 for the entire time. 

I'm agree with you, I want to view my PR on a specific year, not my entire life. Also, when I compare with my friend, I want to compare our performance on the same year, not on our best performance for say the last 10 years.

Glad to hear you agree on this.

More than a year passed since I wrote the original post and my current PRs are very far from what they were up 3 years ago. 

I'd like this too. I have had a bad accident with a fractured vertebrae and I'm unlikely to reach the kind of speed I had before for a very long time.

At one point they had a "best time this year" feature, something like that but for personal records.

Back in October 2022, I wrote you "But if I ever will break one I'll let you know". Well, here I am, at the beginning of this year I smashed a couple of PRs that I never thought I would be able to do. A small miracle. Those were on flat roads, on climbs no way, I am definitely not able but I never was a climber. 

I’m coming back from a cardiac arrest at the age of 63. The biggest demotivator are my old records. With tha amount of damage to my heart I will never get back to my old pbs but would love to start again, without losing what I’ve done before

Me too.  I peaked at 35 and am now 53.  Haven’t had a pr in ten years.  
I miss them.  They motivated me.
