Frequently Asked Questions

How do I train for my first half-marathon?
A half-marathon typically requires 12-16 weeks of training. This is general guidance. Run 4-5 times per week: 2-3 shorter runs (5-8km), one long run building from 8km to 18-19km (about 80% of race distance), and one speed session. Increase your long run by 1-1.5km each week. Proper fueling and hydration become important at this distance.

How many months should I train for a half-marathon?
This is general guidance. If you're already running 20-30km per week, 8-10 weeks is reasonable. If starting from little running experience, allow 12-16 weeks. The longer timeline builds aerobic fitness safely and reduces injury risk. Don't rush the base-building phase—it's where most injuries happen.

What's a realistic pace for a half-marathon?
Half-marathon paces vary by fitness. General benchmarks: Beginners: 7-9 min/km (2:20-3:00 hours). Intermediate: 5.5-7 min/km (1:50-2:20 hours). Advanced: 4-5.5 min/km (1:20-1:50 hours). Most first-timers aim to finish, not set time goals. A negative split (second half faster than first) is a good strategy.

Do I need to do long runs to prepare for a half-marathon?
Yes. This is general training guidance. Long runs teach your body to sustain effort for extended periods and build aerobic capacity. They don't need to be the full 21km—running 18-19km (85-90% of race distance) is typically enough. One long run per week, with adequate recovery afterward, is key. This trains both body and mind.

What's the best way to reach Adelaide events by public transport?
Adelaide Metro buses, trams and trains serve many central event areas, including locations near the Park Lands and River Torrens. Browse events in Adelaide, check the listing for the exact meeting point, then use the Adelaide Metro journey planner to confirm services. For suburban events, also check parking and last-mile access.

What's the climate like for events in Adelaide?
Adelaide has mild, variable conditions. Autumn (March-May) and spring (September-November) are ideal—comfortable temperatures, often sunny. Summer (December-February) is warm and can be dry. Winter (June-August) is cool and may have rain. Most events cluster in autumn and spring. Adelaide's Park Lands provide sheltered, pleasant event conditions. Variable weather means layers are useful.

Where are Adelaide events held?
Adelaide events are held throughout the Park Lands, near the River Torrens, at inner-city venues and in suburban locations. Central routes are often easier to reach by public transport, while access and parking vary further from the CBD. Browse events in Adelaide and check each listing for the exact venue, route and travel information.

Do I have to run the exact distance listed in the event?
Each event sets its own rules. Some allow you to run, walk, or jog the distance. Others accept modified distances or allow you to split the activity across multiple days. Check the event details for specific requirements.

Can I join a running challenge if I cannot attend an event in person?
Yes. Virtual running challenges let you complete a set distance or cumulative goal on your own route and schedule. Check each listing for its participation dates, tracking requirements, and whether the distance must be completed in one session.

How does fundraising work in charity events?
Charity events typically ask participants to secure sponsorships (donations) from friends and family based on their participation or performance. You register, then share a fundraising link with your network. Funds go directly to the charity.

Do I have to fundraise to participate in a charity event?
Requirements vary by event. Some events ask participants to set a fundraising target, while others allow you to participate with just a registration fee. Check the event details to see what's expected.

How do I search for events in my area?
Use the search filters on this page to find events by sport type (running, cycling, walking), location (search by suburb or postcode), and date (this weekend, this month, or a custom range). Virtual events can be found by checking the Virtual & Online filter.
