Running

Stuff I use for running that costs about £10:-

• A buff (useful in summer for soaking up sweat or dunking in water to keep cool, useful in winter for keeping chill off face/ears first thing) - non-kl compliant though
  
• LED arm/wrist/ankle straps (found it useful for running in Richmond Park after dark)
  
  

Posh running socks (in the spirit of stuff they would like but generally wouldn't buy for themselves)?
