conversations.value: For the 2nd kilometer, the donation will be $10 * 2 = $20.
  For the 3rd kilometer, the donation will be $20 * 2 = $40.
  For the 4th kilometer, the donation will be $40 * 2 = $80.
  For the final kilometer, the donation will be $80 * 2 = $160.
  For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $310.
