It didn't all go according to plan, with Birch hit from behind by another competitor on day four, causing him to crash and damaging the KTM.
""I had a hell of a crash, a real big one," he said. "Someone ran into me and off I went. I walked away without a scratch but the bike was quite damaged - the oil cooler was broken. I tried instant metal and that didn't work.
"So I had to strip down the bike and bypass the oil cooler and work some Kiwi magic into it. I lost heaps of time I know, but it was all fixable and luckily I was fine. Of course I wish it didn't happen but it's not the end of the world and I just had to focus on getting on with the rest of the race."
He lost more than an hour, and remained problem free until a nasty incident on the second to last leg in which he was injured - but enough to stop racing.
"There was a big drop off that wasn't really marked on the route book, and it took me by surprise. I jumped about three metres down, and just landed wrong - face planted into the safety equipment on the bike.
"I thought I had broken my nose, and I sort of knocked myself out for a second as well. Not only that I sprained my ankle pretty bad. It was a pretty big one, very scary, and I was quite sore."
Despite a bloody jacket and the daunting task of pulling a motorcycle boot over a badly swollen ankle, he pressed on through the short final stage with just 30km of racing and a 254km transition stage - finishing within the top 30 in his class.
"My goal for Dakar was just to finish, just go there and come home in one piece," said Birch.
"It has been a truly amazing experience from start to finish, I am so grateful for the opportunity to have completed the event. It is totally different to anything I have ever done before and I have really enjoyed the race - apart from crashing!"
