What to wear for London marathon this weekend

Many participants wear old clothes or a bin liner to keep themselves warm while they wait at the starting line up. While April is usually a month where shorts and T-shirts can be worn, old but warm clothes are vital to wear while waiting for the race to start. In mild weather, the TCS London Marathon website recommends wearing lightweight cover-up pieces, such as a long-sleeved T-shirt.

For those wearing shorts and t-shirts, wicking fabrics are suggested that can draw the sweat away whilst also featuring extra ventilation at key body zones (these will differ between men and women).
