Not sure if this is the right place to post this as it's more curiosity than any serious training, but I'm interested in what makes the VO2 max change on my garmin watch. I don't mean "what does VO2 max mean?". I get what it means in theory, but my watch doesn't have the information to actually know that, so the number on the watch can only be a proxy using the information it does have. I'm trying to work out what it bases the number on. All it has is my age, weight, heart rate, speed, distance and incline or decline. I would assume that if speed goes up or heart rate down (for a given distance and incline) the VO2 max goes down, but that doesn't seem to be the case.
I recently did 'Runstreak' (running at least a mile every day for 39 days), and over that VO2 max on my watch went from 39 gradually up to 43. Since then it's come back down to 40.
A couple of days ago I ran 5k, slower than normal and it came down to 40 from 41, but today I've just run 2.5k faster than I ever have and it's still at 40. My heart rate was possibly a little higher than usual on this run, but not much.
I've tried googling to see if I can find the formula that is used, but I assume they keep presumably they keep that secret.
Before anyone asks, no, this doesn't matter in the slightest. I'm not an elite athlete and never will be. I'm not using the number FOR anything. But I am interested.
What are the 3 and 4 year old going to be doing whilst you're running? They're unlikely to be able to run along with you, but you can't really run and supervise them if they aren't?
Do they go to any classes (swimming etc) where you are allowed to leave the building whilst they are doing the class? If so, I'd go out and run then.
Mine are now 9 and 12 and it's much easier, as I can run whilst they are in karate, whilst the younger one has piano lesson and they both run Parkrun. It's much harder with children the age of yours though.
The 4 year old *might* walk/run Parkrun and you could push the 3 year old in a buggy?
Thanks. I tried the lane beside our house and did 30 seconds running up, 30 walking down. Took 5 sets to get to the top and that was enough for a first time! I think I'll try 25 seconds and try to add a set on each week.
I'm trying to vary things in order to get a bit faster at running and thought I'd try some 'hill reps'. I'm in North Wales, so no shortage of hills, but I'm not really sure how far I ought to be running up the hill, how many times etc. Clearly there won't be a 'right' answer to this, but can anyone give me an idea of what I should aim at?
I had a go this morning at running up the path in our front garden. From looking at the stats afterwards, it's about 15metres long, with about 2-3 metres of elevation over that distance, and took about 10-15 seconds to run up. Am I right in thinking that's a bit pathetic and I need to run longer/further up the hill?
Background: I'm in my 40s, overweight (but have lost 3 stone since this time last year so no longer obese!), started running around May last year and have got my 5k PB down from over 37 minutes in May to 31:04 now. I generally run 3 times a week, (but I've just finished a 39 day 'Runstreak' of running at least a mile a day) not more than 5k at the moment, although if I could find the time, I'm sure I could run further.
