I tried spoke and farty pants for 68 like people suggested, but it was still nearly impossible to get 10 secs. What I did was used bones, went backwards from the starting point and did a rear wheelie up the back wall. Was a little difficult still, but much easier than either of the other two. Sir Colin makes everything else pretty simple.
Not sure if this is by design, but if you tie someone higher level than you, you gain points. I'm assuming, the person with the higher SR loses points. I was just playing Proximus and was at 2743 points. At the end, we were both left with Oni and both of us were sub 30 hp left. I had a slight advantage in health and movement, but couldn't really see a way to get anything but a tie, so I moved in to end it. Got 18 points and enough to finish the Playing to Win badge.
