Summer running, happens so fast. The weather's great, the evenings are lighter and all of a sudden it feels a whole lot easier to get those autumn marathon training miles in. Running bliss.
Not to mention the arrival of the big glowing orb in the sky (at least for some of the time) also provides the perfect excuse to do what most runners love second only to running: buying new running kit.
Out with the tights, gloves and winter warm gear and in with breathable, sweat-wicking, technical garb to keep your running - and 'look' - cool.
While you can just stick on an old t-shirt and head out, technical fabrics and innovations have taken running clothing to a whole new level. All the big brands now boast their own heat management systems with impressively scientific sounding names, and while some of it might sound like marketing jargon, there is plenty of science that shows that regulating body temperature is vital for to keeping your heart rate where you want it.
It's also impossible to underestimate the importance of comfort, and of looking like some kind of athletic, tech-fibre-clad ninja.
This is our top pick of performance-boosting summer essentials for your running wardrobe.
