Is it harmful to go from doing lots of exercise to nothing? I’ve just done the London Marathon and would like some rest!

Some people react to an achievement such as running a marathon in this way, while others get the bug and want to run around the world. In fact, scientific research has shown that not running for a week after completing a marathon helps to speed up the process of recovery. This break will also give your immune system a chance to recover so you’ll be less likely to suffer minor infections.

However, don’t treat the marathon as the be-all and end-all of your athletic achievements and stop exercising altogether! Although you may no longer want to train so intensively, regular exercise is vital to your overall long-term health. If you’re not doing any exercise at all, it’s all too easy to put on weight.

Training for a marathon is a huge commitment and once you’re no longer training for it you’ll have time on your hands. Make sure you put it to good use rather than spending it sinking numerous pints or staring at the telly.
