What's it like running 3302.85 miles in 80 days?

If like most, you were inspired by the Olympics but somehow, haven't as yet quite managed to actually pull on a pair of trainers and actually DO something...here's another bit of inspiration -- Jen Bradley (@jenniferbradley), who's 33, has just become the first British woman to run across America, coast to coast. She ran a mere 3302.85 miles in 80 days across 14 states - from Washington State in the west to Delaware in the East. I asked her how much she'd had to run every day.
