It's once a week - what do the TV adverts say....... try it. save co2........
Don't knock it......... it's positive news...........
Just before I changed to my current job, I started the 32 mile each way commute once a week - sick of stuck in traffic (as a long time cyclist).....
Folk at work thought I was superman - nope I was just a weekend warrior, that was once a race cyclist, but job/life had put on 2.5 stone......

I wasn't happy, my nice bikes weren;t getting used.
Anyway did it, but it was a long day - out at 6 am, back about 7 pm, sticking to rigid office hours - was hard - got moaned at by my wife....
Decided enough was enough, then had to convince my wife that commuting everyday was beneficial again (got banned some years previously because of injuries sustained commuting)..... moved jobs, to somewhere within the magic 10 miles - sorted

- injury pattern continues though.....
Don't knock this publicity...... it helps......... bet the guy would like to do it every day, but the time commitment isn't funny, especially if you can't leave work on time.
