Ok, so I blame Lara and Lois and Emily and Lucy for joining.  I'm 57 1/2, doing my first sprint tri at CP in May and another in July.  I'm not competitive (except with myself), but love sport and exercising.  I used to throw the javelin for Barnet.  My day job is as a writer. Only started running a year ago, having told everyone never to run because it's bad for you...have been doing pilates for 6 years, yoga for 3, I'm a later in life swimmer, strong and competent.  Only bought a bike…
