The 10m figure corresponds with the other info in the article.

I assume that "10m-long, 4m-wide" should be "10 km long, 4m wide." Ten kilometers is not eight miles, but it's not too far off.

Ten kilometers is not eight miles, but it's not too far off.

It's 6.2 miles if I remember correctly. I had to run a 10K while in the Army. I'd rather do a 10K volksmarch while eating bratwurst and getting my stein refilled every couple of K's.
