Your inner coach is always talking. But is it helping or hurting? 🤔If you wouldn’t say it to a friend, then why say it to yourself? 🥲➡️💪Love and Mettle,

Why are tempo runs hard?Tempo runs are tough because they▫️ push you into a zone that’s faster than an easy run but not quite an all-out effort.▫️ require sustained intensity at a comfortably hard effort level.▫️ demand focus, as unlike intervals, there’s no break.The challenge comes from maintaining that effort without slowing down, as your legs and lungs burn and fatigue sets in.By gradually introducing tempo work into your training now, you’ll strengthen your ability to hold pace, delay fatigue, and run stronger this summer.Adaptions
🏃 New to tempo efforts? Shorten the intervals to 3 mins.💪 Feel strong running 3 x 5 min intervals? Reduce the recovery time to 2 mins.✅ Ready to build duration? Do 2 x 8 min intervals with 4 min recoveries.Love and Mettle,
Kaz x

Success starts with service and what we can give.

Success starts with service and what we can give.A few years ago I met runners from @sdultrarunning They welcomed me with kindness and warmth. Our trail and ultra running community truly is amazing.I was thrilled to be able to support them with coaching gifts for their annual party and raffle this January, and even more excited to start working with Angela, who won a coaching voucher, and has a 50-mile race in April! Woohoo!When we take steps to lift each other up, our community gets stronger, because when one of us wins, we all win.Whether it’s:
🌲 Putting in trail work to maintain paths.
🏃🏻‍♀️ Cheering fellow runners in a race.
🥪 Handing out PB&Js at an aid station.When we give, we grow.Love and Mettle,
Kaz x.
