Darn, darn, darn!

My sneaky sister seriously took advantage of the fact that I went out of town, and went on a biking streak on Monday! However, have any of you seen any proof of the same? I haven't! Does that mean I won then?

There are eight minutes left before this challenge is over, should I be kind enough to accept late entrances? Though choice, we are talking about €10 here - and the honor of beating your sister in a competition that wasn't really that fair!
