From 2 Miles to Marathon: Fartlek Hill Work for Every Runner

Fartlek Training Essentials: Unlock Speed and Endurance on the Hills

A Playful Approach to Building Speed and Endurance

Fartlek training, derived from the Swedish term for “speed play,” involves an unstructured blend of fast surges and slower recovery intervals. In our 20–40 minute class workout, you’ll use telephone poles as markers for random speed changes while running up a steep 700-foot hill. This mix of spontaneous bursts and steady recovery jogs not only enhances cardiovascular fitness and muscular strength but also trains your mind to stay focused during fluctuating paces.

Why the Hills and Telephone Poles?

Murray Hill presents a unique challenge with its 2.5-mile incline. The constant uphill pushes your lower body to work harder than flat-land running, building leg power and resilience. Meanwhile, the use of telephone poles—varying in distance and location—adds an element of unpredictability to each surge, teaching your body to adapt to real-world race conditions where pacing often changes at a moment’s notice.
