Do you have a steady, dependable, perhaps even a bit too predictable circuit? Or are you the type who likes to mix it up? Perhaps you reverse your morning walk or run (supposedly it’s good for your brain), or just venture out and see where the next 45 minutes take you? When I’m up in St Moritz, there’s a circuit around the lake and if I feel like extending things by 20 minutes I can hang a left into the forest, take in another lake and then pick up the usual path.
