I made a video about this too...
So here's my break down:
Day 1: 3142
Day 2: 10075
Day 3: 10075 (didn't write today!)
Day 4: 13633
Day 5: 15850
Day 6: 22569
Day 7: 22569 (didn't write today either!)
So Saturday was double up day, and traditionally, I have doubled my total word count on this day. As you can see, this didn't happen, but I did double my word count from the day before so that helps! I'm currently just about at the half way point but I intend to write a significant amount today as I have a little more time to write today.
I'll keep you updated and keep an eye on the YouTube Channel too to see further updates.
Let me know in the comments if you're participating, I'm always up for a Twitter word race!
