There are 10 prizes available, as follows:

First prize: GoPro HD Hero 3, Silver Edition

RRP: $469

Provided by Bike Bug

To quote from the GoPro website:

“ The HERO3: Silver Edition boasts the same high performance specs as the famous HD HERO2 camera it replaces, yet it has built-in Wi-Fi and is 30% smaller and 25% lighter. The HERO3: Silver Edition is wearable and gear mountable, waterproof to 197′ (60m), and is capable of capturing ultra-wide 1080p 30 fps and 720p 60 fps video plus 11MP photos at a rate of 10 photos per second.

Second prize: Garmin 510 GPS Cycling Computer

RRP: $275

Provided by Bike Bug

To quote from our review of the Garmin 510:

“ The first thing you’ll notice when you pull the Edge 510 out of its packaging is that it’s considerably larger than its predecessor — nearly 2cm longer, slightly wider, slightly thicker, and heavier as well. In fact, the Edge 510 is nearly the size of the Edge 810 and its predecessors. If you’re familiar with the Edge 500 you’ll also notice that the user interface is slightly different.

Third prize: A one-year subscription to RIDE Magazine (four editions)

RRP: $47

Provided by RIDE Media

Fourth prize: 1 copy of “We Won’t Back Down — On the Road with Orica-GreenEDGE”

RRP: $40

Provided by Orica-GreenEDGE

To quote from the Boffins website:

“ With major wins in the bag from its first year of racing, Orica-GreenEDGE, Australia’s first professional men and women’s international road cycling team, has already made its mark at the highest levels of international competition. This is the story of that year as told through the images of the photographers who have followed the team since its launch, with words from Rupert Guinness, Australia’s foremost cycling journalist. Taking readers into the heart of the team, this behind-the-scenes portrait records the highs and lows of the inaugural year, the very special team personality, and the races won and lost. Big, beautiful and revealing, We Won’t Back Down is a book for every Australian cycling fan.

Fifth prize to tenth prize: 1 copy of RIDE Magazine edition 60 each

RRP: $14.95

Provided by RIDE Media

After stage 19 we’ll go through all the entries and see who (if anyone) picked the winner of the stage. If more than one person picked the winner, first place will go to the person who answered the most questions correctly in the quiz. If there’s still a tie, the person who got in first will win the first prize, the second fastest will get second prize …

If no-one picks the winner of the stage, the person who picks the highest-placed finisher will get the first prize, and so on. We’ll notify the winners by email early next week and reveal the answers as well.

So, without further do, here’s our 2013 Giro d’Italia quiz, compiled by Jamie Jowett. Have fun!

Entries are now closed. Stay posted for the results and prize winners!
