A 15 mile commute each way whcih is doable cycling but I don't fancy running more than a mara to commute to work
Like the idea of seeing how much I save. My car does an average of 53 mpg at the mo.
it would be good to be able to put in details such as commute distance, mpg of vehicle and cost of petrol/diesel (which could be able to be updated as costs change) which then calculates who much you saved on your cycle / run to work.

I've just got in after running 4.15 miles home from work.
I have saved either £1.35 on the bus fare or £2.00 on the Overground.
I suppose over time it might add up, but I won't be doing it every day.

Sorry for the time-lag post... I was thinking about this very subject the other day, following questions from colleagues after I'd run in to work. And I came to the conclusion that it might not actually save money at all to run to work :-o. Here's my working:
By car:
2 x 14 miles = 28m
I get 50mpg or 11mile/litre, so call it 2.5 litres.
2.5 x £1.42 (diesel here in NI) = £3.55
- and keeping it simple, no depreciation (ha! of an 8yo car, as if...), tax, insurance etc..
Running:
2 x 12.5 miles = 25m (more direct route possible on foot)
Rule of thumb for 70kg bloke: 25 miles = 2500 calories
2500 calories = basically a day's worth of food.
I think there's a very good chance that I have to spend more on fuel to run, than fuel to drive.
Can that *possibly* be right?

No because you would need to be eating even if you drive (especially if you have to run later that day too!).

Yup I agree with Curly, that you still need to do your running? So the calories spend running would still be spent driving or not?

But Paul would be burning an extra 2500 calories running back and forward to work so he would need to replace them to maintain his current weight. Depending on what kind of run he would normally do lets say maybe 7 miles? So normally 700 calories to make up but then that is still an extra 18 miles / 1800 calories. It very possibly would cost the same!

Safe to say I wouldn't otherwise be doing 25m on a school day, these are bonus miles. Or at least most of them are. And dd's also right that my 2500 calorie calculation (guess-timate) is *extra* above just 'existing' calories.

Paul you can do alternating runs, eg
* monday morning car
* moday evening run
* tuesday morning run
* tuesday eve car
That way you don't run too much and you save money

Do you eat back every extra calorie (minus BMR as dd says)?
And what the bloody hell are you eating that costs £3.55? Easiest way is to add extras to what you are already cooking to eat that over and above. Then we should be talking about £1-2 max, including extra fruit/snacks.
