2020 Your Best Writing Year Yet...

The Two Marks (Desvaux and Stay) are the co-hosts of The Bestseller Experiment – one of the most popular writing podcasts on the planet, with over half-a-million listens.

In the first year of the podcast, they challenged themselves to write and publish a bestseller. The result? The time-travel, rock n' roll, chart-topping BritCom - Back to Reality!

Three years on, they have amassed 250 hours of interviews with bestselling authors who have collectively sold over half a billion books (yes, billion!) Authors include Michael Connolly, Ian Rankin, Joanne Harris and Walter White himself, Bryan Cranston. In all these interviews, there is one piece of advice that keeps coming up...


But Writing Every Day is Hard...

It is! Most who try, fail. In our studies, 83% of writers cited not having time to write as THEIR NO.1 CHALLENGE. So Mark Desvaux, coach and habit geek, ran an accountability experiment, firstly himself, then with a larger group of writers ("Experimates"). The results were astonishing:

  • “Experimates” reported ten times their word count.

  • 90% of participants reported feeling more accountable.

  • 100% of writers loved the challenge.

...and Mark wrote more words in two months than the previous year.

Why 200 Words?

  • 200 words is around one page in a book​.

  • Write 200 words a day and you will amass 73,000 words in a year, the average number of words in a published book.

  • From our studies, 200 words a day is completely achievable:

    • It's an average of 15 minutes a day.
    • It's the equivalent of two emails or six text messages.

  • But we'll let you in on a little secret we discovered before you even start. The 200 word goal is the daily minimum. Our research shows that actual word count is higher, for example, you might even manage 2020 over a week (just saying....)

What Writers Are Saying


Having difficulty writing every day? Do this challenge

I really enjoyed this. Any writer having difficulty writing every day… do this challenge.

Debbie Clifton, Canada

Mark my words, you will complete that novel within twelve months.

A napkin in a café, frantically scrawled in sand at the beach; wherever you are, no matter how busy your life is, you will find a place to get that daily word count down. Mark my words, (this is a long testimonial because I'm including it in my word count), you will complete that novel within twelve months.

Andrew Chapman, UK (author of The Accidental Scoundrel)

Really showed the value of holding yourself accountable

The writing challenge was awesome. It really showed the value of needing to hold yourself accountable. I enjoyed this experiment immensely.

Jonathan Lyster, British Columbia

I've built up a good habit to carry me forward

I've built up a good habit to carry me forward and turned off my compulsive inner Editor to get that word count done. I highly recommend the Writing Challenge to anyone who is struggling to just "get it done".

Sandra A Hunter, Canada

I was writing more words each day without thinking it was an effort

I found the challenge a great way to pick up momentum again as my writing was in a real slump. Towards the end of the week I found I was writing more words each day without thinking it was an effort. I think being accountable was the real clincher for me, as I work much better to an imposed deadline, and setting my own has never been particularly helpful.

Jac Harmon, Cambridge, UK

A huge confidence boost

The writing challenge was a huge confidence boost. A simple idea, yet it reaped huge benefits, motivating me to write off piste. It provided me with a sense of achievement.

Rachel Howells, UK, Author of Wode House


It was great to see my word counts climbing through the week, and to see my weekly total end at almost 10x the previous week.

Sage, South Africa

Kick start you Writing Habit

Great way to kick start a writing habit, especially if you're not sure how to begin.

Robyn Sarty, Canada

If you want to build a long-term writing habit, 200 words a day is a good way to do it!

An enjoyable, low-pressure experience that helped get the creative juices flowing. If you want to build a long-term writing habit, 200 words a day is a good way to do it!

Julian Barr, Australia

Better than other writing groups and challenges

I thoroughly appreciated taking part in the Challenge, a helpful and fun motivator. Better than the writing groups and challenges I’ve tried.

Richard 'Bat' Brewster, UK

The Challenge is in Open-Beta.

With your help, it will remain all-inclusive.

As the BXP2020 Challenge is in Open-Beta, we want it to be free for students, those on low income and those who want to "try before they support."

However, you know us... we LOVE a good experiment! If you can contribute to the running of this challenge, we have an interesting twist... We call it the "Gym Membership Effect". Research shows that when people commit financially, they have a much higher success rate.

Once you have tried the Challenge and see the benefits, we'll invite you to pledge a nominal amount to help support and grow the project and also receive some wonderful goodies in return.



The BXP2020 Challenge will prove to you that no matter how busy your life is, if you commit to writing at least 200 words a day towards your book, you can finish it in a year or less. And if you accomplish this in 2020, maybe you can do it for the rest of your life? Just how many books could you publish?

Let's be honest... When is life ever going to get less busy? It is not about how busy we are, it is about making a commitment to ourselves, getting in the writing habit and also a little encouragement from The Two Marks each week!

Don't die with your words still inside you...

As one participant said... "No more excuses!"

What’s more, by taking part you will help...


Your word count will contribute towards our Community Challenge to collectively write ONE BILLION WORDS! To make this a reality, we have 15,000 spaces for this challenge, so tell your friends and get them to sign up today.
