MURO LECCESE (Lecce), Jan 31, 2007
From F1 to Karting. Michael Schumacher arrived today in Salento for a 2-day trial with Toni-Kart team, a top notch kart racing team from Brescia, set on the "La Conca" circuit.
At Muro Leccese the german wore a bright racing suit, red shoes and helmet, and went for a practice session.
He started alone, then a few other pilots joined him after 20 minutes of practice.
Schumacher showed great interest in the mechanic team's work and offered various advices for the setup of the vehicle on which, as a kid, he began to get closer to the motorsports world.
No lunchbreak for him, just a sandwich between a practice lap and another. We do not know if these trials in Salento may evolve in a constant future effort in kart racing.
Today's one was the second test that Schumi did on the light racecars after the first that took place in Lonato (Brescia) in the past december. In 2002, always in Muro Leccese, for the recurring International Kart Racing Championship, the german already had a few practice tests.
Following rumors in the karting world, there is still the chance for Schumacker to get back to kart racing starting on May 13th for the WSK International Series, category 125 kf1.
Old news.
