Grand Slam

Grand Slam Challenge Series 2020

Due to COVID-19 and in accordance with our Response Policy, we regret to announce that;

Grand Slam #5 on 11 October is now cancelled 

We will advise regarding 2021 dates in due course.

But you can  of course ride GS#5 unsupported – See Route Map tab below for information on riding the Grand Slam # 5 route UNSUPPORTED


Our Policy Surrounding COVID-19

Between February and October there are five recreational challenge rides throughout the Adelaide Hills, Barossa Valley and Fleurieu Peninsula as part of the Grand Slam Challenge Series. Participants can ride in one, two, three, four or all five of the rides. Each ride combines two different loops of between 40km and 100km, all starting and finishing in the one location. There is also a Mini Slam for those looking for something a little less challenging, in which participants complete only one of the two loops.

Build up your fitness and increase your endurance throughout the year to complete the ultimate Grand Slam Challenge in October, or join us for one or two rides of the year. Meet new people or meet up with old buddies. The Grand Slam Challenge rides are as much about the ride as they are about the people you meet.

So whether riding your bike through the Adelaide hills towards the big 200km is your goal for this year’s Grand Slam, or actually climbing through the Himalayas, your only chance is to sign up now.

And if you sign up for the series and are a Bike SA member, you also go into the draw to $250 Roof Rack City voucher www.roofracksa.com.au

Preparing Your Ride

Resources to help you prepare for your ride:



What time does each ride start?

Official start time for each ride is 8am (6.30am for Grandslam #5). There will be a rider information & safety briefing 15 mins prior to the start.

What time do I need to register by on the day?

At the start location/registration desk collect your Grandslam Rider ID which needs to be attached to your shirt or your bike. This will enable you to access the refreshment stops and then needs to be handed back at the finish so we know that you have finished your Grand Slam/Mini Slam ride. Registration opens from 7am (or from 5.30am for GS#5)

For Mini Slam riders – you can select to ride Loop 2 and have a later start time of 10.00am (no later than 10.30am) should you wish to have a sleep in!

I have registered for the Mini Slam but would like to ride the Grand Slam?

No problems! You can choose to ride both loops or just one depending on how you are feeling, etc. The ride is the same price for 1 loop or 2. No need to let us know beforehand. Please advise us when you register on the day what distance you wish to ride/have ridden

Where is the pre-registration?

The start locations in each town will be signposted as you drive in. Plenty of parking is usually available. Just allow yourself time to park/gear up and pre register by 7.45am for the Rider Briefing (or 6.15am for GS#5)

What sort of food/drinks are included?

Refreshment stops are normally midway on each loop. You will see signs pre-warning you of the stop. Here you can enjoy a tea/coffee or water/hydration product/fruit juice – biscuits and fruitcake/bananas to refuel! Lunch is available after Loop 1. You can make your own roll – plenty of fillings to choose from! And the famous apple slice will all help you recharge after your Loop 1 or before you challenge yourself further on Loop 2. There are vegetarian and gluten free options available – just indicate this on your registration form.

What if I have mechanical problems?

Pull your bike to the side of the road/turn it upside down and call one of the support mobile numbers listed on your route sheet/map. There are ride marshals who may be able to assist or the support vehicle can collect you and your bike should you be unable to finish. Please note: we recommend that you carry at least a small tool kit with spare tube/tyre patches and you know how to use them. Please refer to the Be Prepared resource for more information on how to making sure that both you and your bicycle are in top condition for the ride.

What should I wear?

Check out the weather forecast or email updates from Bike SA – as we are riding in the Adelaide Hills the weather can change quickly. Arm warmers and a light rain jacket are great – layering is always useful as the temperature does increase/decrease on the day!

Are the roads closed?

No – the Grand/Mini Slam series is an open road event. You will be sharing the road with traffic – so usual SA Road rules apply including riding no more than two abreast and then only when safe to do so. Otherwise ride single file, particularly on narrow and winding roads. Be aware of your position on the road and how visible you are to traffic – both oncoming and approaching from the rear.

The route is clearly marked with Bicycle SA red arrows which are easy to follow. Copies of the map and route notes are available at registration and in the interests of your safety, please take a copy with you.

Be rider aware and warn your fellow riders that you are overtaking – a simple comment “Passing” is recommended. Please do not litter – take your rubbish home with you!

Do I need to let you know when I have finished or if I withdraw during the ride?

Yes! So we know not to send out a search party for you, please sign back in when you return from each loop. This will enable us to keep track of how many riders are out on the circuit and help ensure everyone has returned safely. If you decide to withdraw part-way through the ride and go diectly home or have someone collect you, please call the telephone number for the Grandslam Base which will be printed at the bottom of the route notes.

I find it's a great way to challenge yourself throughout the year. It gives me a lot of motivation to keep cycling through the colder months and it's really well organised.
