This running block focuses on developing your threshold pace, the fastest speed you can sustain while still maintaining control of your breathing and form. Threshold work sits just below your red line, where effort is strong and concentration matters, but you’re not in an all-out state. It’s about learning to stay relaxed and efficient at a challenging yet steady intensity that you can realistically maintain for 30–60 minutes in a highly motivated, one-off situation, such as a race. By breaking the intensity down into manageable chunks, this type of training builds the engine that supports consistent and confident race pacing. Your sessions will include sustained threshold runs and continuous tempo efforts broken into manageable blocks with short, active recoveries. These structured intervals will hold you at or near this effort without tipping you over. The goal is to run with rhythm - steady pacing, tall posture, smooth stride, and strong breathing. We’ll prioritise consistency over speed spikes, keeping every rep controlled so technique stays sharp as fatigue builds. This block enhances your ability to sustain a strong pace for longer, making race pace more comfortable and sustainable. By lifting your threshold, you’ll hold faster speeds with greater efficiency, recover more quickly from surges, and maintain form deep into a triathlon run when fatigue starts to bite. Coming out of this phase, expect to feel more composed at tempo efforts, more confident in pacing, and better equipped to finish races with strength and control.
