There is an excellent series of articles this week in the Racing Post about what to look for in the paddock - i.e. when horses are parading before a race. Membership is required but it is free. Once you have signed up, click on the Racing Header, go to News - Cuttings Library, and search for 'paddock watching'. Assessing whether a horse is fit is not the easiest the thing to learn, but once you know what you are doing, it should make a big difference to the success of your betting.
