Normal sudoku rules apply.

Each circle represents a different driver. Find an orthogonally connected Dutch Whispers line which defines a racetrack. Neighboring digits along the Dutch Whispers line must differ by at least 4. The racetrack must form a closed loop and cannot cross or touch itself (i.e., each cell on the line must be orthogonally adjacent to exactly two other cells on the line). Each driver must be on the racetrack with their current position in the race respresented as the digit in their cell. Additionally, the racetrack must pass through the three checkpoint squares which contain the digits 1, 2, and 3.

Digits separated by a V sum to 5 and digits separated by an X sum to 10.
