I'm not going (even though I live only 10 miles away). Donington Park is on the escarpment above the Trent, so they could have a seriously undulating course if they wanted to. But I couldn't find any information about the course on the website.
Oh, and Donington Park is a long way (well, 20 miles) from Leicester. Swim across the Trent from the Park, and you're in Derbyshire.
