Founder Dr. Ron Hill won the Boston Marathon over 50 years ago, and since then developing gear fit for the ultimate race has been something of an obsession for Ronhill. The outer short, in a relaxed fit, stretches brilliantly to let you run freely. Carrying fuel and essentials on a long run shouldn’t feel like a long haul – there are carefully designed 2 drop pockets for gels, and a secure pocket at the back too. A new print can be found down the sides. A lightweight performance mesh inner keeps you cool on warm days. Two hidden thigh pockets are great for essential items. The fabric provides the optimum balance of stretch and support. The Tech Marathon Twin short is built to help you feel like you can run forever.
