Definitely agree with Venom... Steve appears to be male.
Left field recommendation is London City Runner - about 20 minutes walk from Waterloo.
Head to IMAX cinema, east along Stamford Street, north over Blackfriars Bridge to Ludgate Circus, Right up Ludgate Hill - right between Starbucks and wine bar with Champagne bottles on window-sills. LCR is about 20m along on the left...
