Simply chunking up your body fat isn't the answer, simplistic as though it may first appear. I know. I've been living with the issue for all my adult life. There have been times when I've been a stone heavier or a stone lighter, and it's not made a sparrow fart's difference.
Between September and April there will be a time during every day when I lose all the circulation from the end 2 joints of my fingers. When it's bad, it can be worse. But here's the thing: I can warm up, and it's not usually painful. Not even pins & needles. As stated in the last paragraph above, avoidance is preferable. Moving to Egypt is an option. An extra layer is good, eg a Merino wool base layer. Having a warm bath before bed helps get an extra hour's sleep as you're not simply trying to get warm to start with. When running, the trick is to start warm. Wear a beanie hat and gloves in winter, and pocket them after 2 or 3 miles. Layer appropriately, and take off layers as you feel the need. You can tie them around your waist.
One other thing. Ignore Vdot52. That forumite hides behind a blank image and is a mere troll of the worst kind.
As a Manchester United supporter, I can't wait to talk to my Dad, who supports the other side.
Hilly, I can strongly recommend investing in Merino wool. I froze all last winter, but got a base layer for cycling this season. Oh what joy. I have even used it under the wetsuit for a brief dip in the lake on Boxing Day. It did brilliantly then, too. In fact, if it's proper cold I'll grab it at the weekend as well.
Today, bike day, was cancelled. Too dangerous for group riding. I did rig up the turbo in the garage and did 1x Top Gun ie 90 full on minutes for a 30 mile outing (inning?) at reasonable pace. Didn't fancy a run.
^^^^^^^^^^^^ Er, didn't you miss the famous Pirate, of this parish. Crazy Sid Sidowski. Not content with tackling the ironman distance triathlon t Nottingham, known as the Outlaw. Sid (as he is cunningly known) decided to do it on a BMX. Bless him, he also carried a load of timber to help the cause....
-yes he had to get permission first, oh you tedious pedants....
Saturday is bike day. 56 miles with the gang, including plentiful Forest hills. Done inside 4 hours, and I was still feeling fresh. Sometimes I'm toasted. After lunch I sat down and fell asleep, waking to find the house empty! A very odd feeling. It's a fairly lovely day down here AOH. We haven't had any of that white stuff this winter, although it was a bit chilly first off, and breezy. Blue sky now.
I really don't understand why people are travelling hours to do a 20 minute run in a park. I find it most odd.
