If you ask a doctor, they'll tell you regular vigorous aerobic exercise is the best thing you can do for your overall cardiac health. That's why the debate on "do I go long or go short/more regular" has largely tilted in the last few years toward the latter.

You are right. That was AA (after attack). I get a little testy when my intent is misinterpreted.
Merry Christmas everyone. Stay safe both on the bike and off. (Oops, there I go with the unsolicited advice again.

Update;
Tire was down again this morning. Checked, and the new hole was 2 inches away from the patch put on yesterday. A fine tooth comb check of the tire surface revealed a tiny metallic foreign object, barely visible to the naked eye. It wouldn't come out with hand pressure, or with a pliers, and it eventually took a pair of tweezers like these;

to get it clear. A 2-3mm long piece of wire, possibly from a frayed brake/shifter cable.
No visible damage to the outside of the tire otherwise, so gonna take it out again tomorrow am and see how things go.

Of course, but I was simply referring to the search and diagnostic aspects of the job. Patience and perseverance.

Could well be that. You'd presume it's road debris rather than anything I'd pick up at home. Can't imagine how a piece like that would force its way into the rubber without being rolled over at 20ish mph.

Yup, something not a million miles removed from that.

I think if you read up, you will see it is a myth. The myth is that in TOTAL this burns more fat. What multiple studies show is that by exercising in a higher range (hr power etc) you will over time burn much more fat than exercising in the so called fat burning range. Over time, is lets say 24 hours. The higher intensity workout raises your metabolism significantly higher than the fat burning range, so over the next day you burn off more fat, than the hour you spent in the fat burning range.

I went this entire season flat free with GP4000's. When I first mounted them on new rims I was getting flats all of the time. The culprit was cheap rim tape. I replaced it with better and slightly wider tape which solved the problem. Perhaps the OP's tape has moved and the inside of the nipple is exposed. Try replacing the rim tape.

I will keep an eye on my rim tape, but this round of flats were all definitely on the outer side of the tube. Thanks for the suggestion.
