Women haven't just taken part in ultrarunning history. They've helped shape it.
From Mavis Hutchison taking on Comrades when women weren't officially allowed to compete, to Ann Trason dominating Western States, Courtney Dauwalter Courtney Dauwalter redefining what's possible and Rachel Entrekin becoming the first woman to win Cocodona outright and our own Sarah Perry showing what is possible!
Different generations. Different distances. Different barriers.
But every one of these women pushed the sport forward. Now we have organisations such as !
And this carousel only shows seven of them.
Who would you add to the list?

Let's talk numbers.
Like everything else, our costs go up every year. Race insurance, venues, food, portaloos (yes, really), the list goes on.
So from 1st September, entry fees are rising by around 10% across the board.
We're not going to pretend that's nothing. But we are giving you fair warning and a proper window to lock in the current price before it changes.
Enter before 1st Sept, pay what you'd pay today.
The secret's on the sign. Keep going. And get in before the price increases.

You've had that 100 miles in your sights. It's not been plain sailing. Your body and your mind have wanted to give in and take the DNF but.... you keep going. The legs keep taking steps forward and you do it!
There are easier ways of getting to 100 miles, but that's exactly why it's such a milestone in the Backyard.
Can we tempt you?
12th September - Thetford Forest Backyard Ultra Festival
