Here you go:
15:20 to 15:30
I ride a Norco Four Crosser and it is beautiful. The duallie suits this track so much,
i'm so glad im not on a hard tail.
(duallie=Dual Suspension bike - i.e. bike with both fron and rear suspension. Hardtail = a bike with no rear suspension, i.e. no suspension on the rear wheel).
22:00 to 22:27
She speaks so fast, I do not understand anything. Could you please transcribe what she says, please.

-> I knew I was going to have a bad gate (=bad start), so my intention was to go inside,
and then I saw Horakova and Jill Kintner go inside, so I kind of backed off a little bit, and I think Anneke saw what was going to happen as well so we both kind of swung wide and braked a lot and stayed out of trouble and just went around them when they crashed...
Interviewer: A little ladies luck?
Well, yeah, its good for me because I ride downhill a lot so the drifting turns really suit me
but like I said my gates were terrible so I'm pretty happy.
22:29 to 22:48
What is a gate? What does it mean to "have a bad gate" ? (Gate is the thing that is used for the start in 4 cross racing, like what you see in motocross as well. A bad gate is a bad start).
22:57 to 23:10
Yeah it was a pretty good gate but Graves was still faster than me, we got tangled on the first straight, then Roger came by I guess, well, he led, and then last turn he went too wide
and I saw a gap and I went for it, so...crazy.. (
interviewer: happy?)....yeah, awesome...
25:28 to 25:42
Pretty tough, we just started our own deal and you know to get, just to have a clean run,
I'm stoked, you know. The track's great, the crowd is awesome, I was just having a good time coming down the hill, you know...
OK, hope that helps. Let me know if you STILL don't understand all the words...

(not easy with all those accents and weird downhill language...).
