I got out for almost 32 miles this morning, very windy and 359m of total ascent. This is how confusing this is - mix of miles for distance and metres for measurement.

I have also just upgraded my bike computer to a Garmin Edge 1030 Plus from an Edge 500. It gives me loads more data, but have to question how it calculates some if these things.

Anyone know how it knows and calculates how much fluid lost and how much fluid consumed and also how it calculates how many calories consumed?

I drank about 1.6 litres and it thinks I put in 2.1 litres, and I consumed about 150 calories and it thinks I consumed 600. I have not put in any data for this, it just reported this data.

Any ideas?
