I've been reading one of Bob Glover's books, and very good it is too.
It's confusing as well though. Why do you Americans talk about times for 5k and 10k runs, then give your pace in minutes/mile??
I'm from the good ol' Europe, but started running here in US. Pretty much like languages (English and Italian) I use both systems depending on situations. For running I simply can't pace myself in minutes per kilometer-- I have no feeling for it.
So it happens that when I'm talking with my Italian runner friends, we have to translate back and forth between British and metric systems.
I think I use every system going at different times.
As a Brit raised at the time they tried to convert everything to metric, now living in Canada! I use feet and inches for height, meters for size, kms on water and when running, miles for driving and speed, weigh myself in stones and now in pounds, weigh other heavy stuff in kgs, cook in ounces and now in cups. I drink pints of beer (now I drink sleeves but I don't know what they are), fluid oz of water, and work in litres for everything else.
Chaos I tells ya!
But yeah, I totally agree, I get myself tied in mental knots trying to work out my pace & speed from a run!
We talk about times for 5k and 10k runs, because all the races are measured in Km. When I do my training runs, I do my times in miles because that is the measurement I'm familiar with, and makes sense to me.
Now, why do the races in USA do their distances in Km? I have no idea, unless it's to conform to some international agreement.
my experience as a runner in NYC is that very few races are in km, and most are in miles. That is, I've raced one 5k (which was actually truly a 3M) and I'll race a 10k in July, but all the rest are 4M, or 5M. Obviously I'm not considering Half-Marathons and Marathons, whose distances don't make sense both in km and in miles.
Only for you guys. I do races and paces in kilometres. My meagre mathematical skills would be sorely challenged if I tried to work under two different measurement systems. You guys must be mathematical geniuses.
Stick with what you prefer over distances- I think Americans enjoy using Kilometeres because they like high numbers; 10km looks longer than 6.2 miles - 6 points for a 'touchdown' ( when a bloke in a padded suit and crash hat does anything BUT touch the ball down) as opposed to a single 'goal' or a meagre 5 points for a 'try' , three points for a 'drop-goal', three points for a 'penalty' and just two for a 'conversion' - scored by blokes with cauliflower ears and no body armour.
Can't understand why yanks don't play Cricket...........
Miles better.
Why bother with splits? - do your distance, 3,5,12,26 miles and compare times for the entire run!
.....Not according to the other comments on this thread, apparently!
I think most people in the States and the UK equate distances in Miles because it's something you can get hold of - let's face it, if someone tells you a certain town is 76km away, it dosen't mean anything, if they say 50 Miles, you have an idea.
