Hi.

Anyone seen or used this before?

http://www.mycyclinglog.com/

Its very good, I log nearly every ride I do on here, very good for keeping track, done 871.31 miles since begenning of april and it calculates the averages and divides the month and everything, very good and since I have been using my cycling log it has allowed me to see improvements I have made over the past couple of months :)

I recommend giving it a go, really usefull tool.

Hi Will (fellow anorak)

I used this site when my usual one was "down" for a month and agree that its good. I've been logging mileage on cyclogs.org since the beginning of 2007. Since it has a "leaderboard" and your progress is (sort of) public, it helps keep your nose to the grindstone. As well as raw mileage there's all sorts of other fields to fill in and I've since dispensed with my old traditional paper training diary.

871 miles (are you really accurate to 0.31? You're obviously not a since student :wink: ) in 5 weeks is a good effort!

Is there any way to get your data back out of the site? My worry with web services like this is always what happens when they vanish from the net

Well, they allow you to download it all as a .xls file at any time and this was even available at the time last year when the main site was down. But, of course there's always a level of trust with these things. Certainly, the guys running the site appear totally obsessive about it all - is that a good thing?

As an aside, Cyclogs has a "team" section, though not looked into it..... I presume this is a way Clifton could compete with Tromso Wheelers.

If they let you down it, problem solved. I've been burnt before losing data when online services suddenly get bought out/go bust/vanish so am now careful about such things.

Thanks, what do you mean about the accuracy? Like 871(.31) bit? I just like to count that bit as if I have done just 10 miles it could be almost 11 miles. I'm an IT student :p. I rekon I could add or subtract 50 miles from what I have got on there, I have had some rides I have not put on and sometimes my speedo just goes totall mental picking up other signals I just put it on to the best I remember it or dont bother.

I will try cyclogs.org too, never knew there was other log sites.

I'm sure that if a few of us register we could get a decent mileage total - not sure we can all match your average speed though Rob!

Exactly, so why quote two decimal places? But never mind - 871 miles in 5 weeks is 174 miles/week or 9000 miles a year - keep it up!

As Rob says, not a science student then :)

What fun on a Friday afternoon!

But it remains deeply worrying to me this business of doing decimal fractions of miles! Anyone know how far exactly .791 miles is?!

Much better scupper this miles lark once and for all and re-set all your gizmos to metres and kilometres. An obvious benefit is that all your speeds and distances will increase by factor 1.609! So much more impressive at no extra effort!

I'm confused? Its how my speedo shows it (0.000) and I cant change it. Fine, I did 11 miles today at 17.6mph average, I'll still do the .6 in mph though as its significant.

At the risk of involving grandmothers and egg sucking, here's how it works:

Your speedo reads distance with three decimal places, but it's not actually accurate to that (even without it going crazy/off occasionally due to interference) unless you have accurately measured the circumference of the wheel with you sat on the bike (see http://www.branfordbike.com/computer/comp10.html for a method)

You can work through the maths by working out how much a small difference in circumference affects the calculated distance for a set number of wheel revolutions. Your speedo is probably accurate to 2 decimal places for distance, but not three without any drops/mad figures from interference.

For the speed, the .6 is significant and valid, but it's also two orders of magnitude less accurate than the claimed measurement for distance, so that's not so surprising. Again, the maths to calculate the error is informative.

The moral is that actual measurement accuracy isn't equal to the number of decimal places on the display.[/img]

When I set up my speedo I put in 2145, someone in my street did some maths or something to make sure it was the right value, so if I said 11.7 miles is that ok?

I'm regretting starting this.

Will, you've put in a circumference of 2145mm. With the best will in the world this is an *estimate*. You don't know what the exact circumference is. You can be fairly rigorous in measuring it (follow Arthurs link), but even then you'll be +/- 2-3 mm. The exact circumference will then, to an extent, vary from day to day depending on, for instance, tyre pressure, air pressure, rider weight, tyre wear. And if you change tyres, well......

But, anything around 2100mm is close enough. Just quote/record your distance to the nearest mile (which on a long ride is bugger all difference as a percentage).

What's a mile anyway? What's a km? We're sat on a sphere hurtling through space.....

Its too nice a day - what am I doing sat here at my pc anyway!! :roll:
