Tuesday night's practice session for the Isle of Man TT started off with the fastest lap of the week so far. Guy Martin took his Superbike Yamaha round in 18 minutes 14.58 seconds - an average speed of 124.09 miles an hour. Martin and Ian Lougher were the first two riders to get the session underway and Lougher's Superbike Honda was less than ten seconds behind at a speed of 122.989. John McGuinness and Ian Hutchinson also completed their first laps of the night at over 121 miles an hour. Martin's second lap was even faster than his first, knocking five seconds off his earlier time and recording a speed of 124.717. However, the best was still to come as McGuinness posted a lap of 18 minutes 9 seconds - or 125.267. Lougher and Hutchinson both increased their speeds to more than 123 miles an hour on their second circuit of the night - while Bruce Anstey was another 123 man, as was Jason Griffiths.
