Hi ,
It looks like you're using an ad blocker.

The revenue generated from the adverts on the site is a critical part of our funding - and it's because of these ads that I can offer the site for free. But using the site for free AND blocking the ads doesn't feel like a great thing to do, which is why this box is so large and inconvenient. Some sites will completely block your access, but I'm not doing that - I'm appealing to your good nature instead. Did you know that you can allow ads for specific sites, whilst still blocking them on others?

We recognise that gender classification is not a binary choice. However, the only age grading data available is restricted to male and female options. Rather than pushing you into making a binary choice, we've provided all the available results. We definitely won't be using pink and blue.

How Age Grading Works

Age Grading (aka WAVA) uses male and female world record information set by people of all ages. When rating your race time, it takes your age and gender into account. Olympians and world class athletes tend to score close to (or even above) 100. The rest of us won't be so high, but it's a good way to compare performances by different people.

Here's an article about how age grading works.
