    Depends on the course. You should notice the weight loss if they send you up hills.



    On the flat it seems to be all about the power. I'm always getting passed by 'bigger' blokes.



    Now running on the other hand - as Treefrog says 'skinnier = faster'.

    I was actually being a little serious, there are so many other componants to becomeing faster/stronger on a bike.





    I would swap your 5kg in fat( or the 5kg you want to lose)



    for



    5kg in muscle.



    However as muscle weighs more than fat, you might lose 5 kg or at least turn it to muscle and you would never know.



    The point being, forget losing weight, go ride 20km ( a standard distance for a sprint tri), and time yourself , do it race pace, then every few months time yourself again, if you faster your getting better.



    There is no substitute for for training hard.

    Conehead suggested hammering a 10mile TT - i'm off to try and kill myself on Sat...

    For running, it seems like 2-3 seconds/mile/pound you lose, which really makes a big difference when you lose 5kg

    We have not yet introduced the potential into kinetic energy argument with regard to the downhill aspect.Most feed stations on long courses are at the top of the climbs so load up on bottles and supplies and see your speed become that of coneheads light speed without the use of naked black carbon.

    Not wanting to get into a massive debate about it but



    Thats absolute rubbish



    If a 6.2 inch man who weighs 500lbs were to lose 1 lb and by your therory he would save 2-3 seconds per mile.



    What if a 4.0 ft man who weighs 100 lbs were to lose 1lb would he also save 2-3 seconds per mile.





    Logic says my friend of course not.





    There are hundreds of things that affect both cycling and running, before you even get to the how to save time etc.



    Running or cycling technique for one

    Equipment used for two

    level of overall fitness, three.

    The weather, four

    How much training has gone before, five

    Diet, six



    I could go on but i wont,



    The only thing that is going to get you faster and quicker is more training, the weight loss is part of training.



    If you look at almost all professional athletes doing any sport they eat like bloody race horses all the time, and this gives them the energy to train harder and for longer.
