Brick sessions are a great one to add to your training over the winter. Getting your body used to moving from bike to run, especially on tired legs, can make a big difference when race season comes around.
So why not practise now, build the habit over winter, and be ready to put it into action next year? 💪

The more comfortable you are in aero position, the easier it is to stay there on race day. 🚴💨
