When you should be using ice baths is fairly up in the air and also lacks real strong evidence they even work. One thing is for sure, if you did any kind of weight training you should skip any kind of ice bath as it will slow any recovery
and in some, increase muscle soreness the following days. It should also be avoided in preseason and preparation phases of training, as it has been shown to slow training adaptations. During those times an active recovery effort has been shown to be just as, if not more effective.
So the right time to take an ice bath is a multi-day event but if you are just training in the off season it is likely better to skip it for the time being! If you still have questions or looking for help on how to plan your training plan around peaking and using ice baths, cycling coaching
may be right for you!
