From Burbank to Cypress, California.
Distance: 34 miles
Time: 90 minutes.
I used to commute from L.A. (the 405 and the 10, just north of Culver City) to our offices across from The Block At Orange. I think it was like 43 miles.
It took about an hour on a motorcycle. 
75 miles, from Orlando to Palm Bay FL for around 3 years. Outside of the rush hour it could take only a bit more than an hour if you were willing to go more than 80 on the interstates and the lights smiled on you. But during rush hour it was more like an hour and a half since it wasn’t possible to go more than 75 on the highways and there was traffic on the city streets as well.
Just popped in to say SAN DIMAS HIGH SCHOOL FOOTBALL RULES!
(You know you were all thinking it!)
I’m not even going to mention my work or school commutes and subsequently my 10 years of working from home. You all will smack me with a trout.
My longest commute was about 25 miles/40 minutes one-way between Brazoria County, Texas and Houston on 288 (the Nolan Ryan Expressway). Not a bad trip, but I suspect the backups during rush hour are worse now.
Current commute takes about 10 minutes, no highway driving.
Roundtrip 66 miles to commute to grad school. I actually quite enjoyed the drive–nice scenery, longhorn cattle in the morning mist. The hardest thing was finding an appropriate parking spot, and it was very complex. You paid for certain kinds of stickers which entitled you to park in certain lots. I had a commuter sticker, which was the lowest of the low, and often all the lots I was allowed to park in were full. I often ended up walking over a mile from where I parked, which was most annoying as it meant I had to carry all my stuff around. This meant I had to leave my house approximately 2 hours before my earliest class. However, I only had classes MWF.
Midway through my second semester I moved so I could commute by bike. Much better.
My longest commute was when I was living in Dansville, NY and working in Albion, NY - fifty-five miles each way and none of it via expressway. Took me about three hours of driving each day. Fortunately I only had to do that for a couple of months.
I commuted from Middletown, NY to Beacon, NY for a couple of years. That was thirty-two miles each way but mostly on an expressway so about a forty-five minute drive.
On the plus side, I didn’t work day shifts so I never got caught up in rush hour traffic.
My commute wasn’t ever to bad. At most, a half-hour each way. But one time a few years ago, it took two hours to get home. It did snow, but it wasn’t that much for Ohio. It maybe snowed an inch and it took an 1:30 longer to get home. That made me realize I could never live in a bug city that had a lot of traffic or you needed to take public transportation.
My boss and a few coworkers at the job did have a daily commute of about an hour each way. My boss has worked at this place for probably 8 or 9 years. And my mom knew a lady that moved to Texas from Ohio. She had a daily commute of about three hours eachway. I don’t know how long she did that. I think she lived with family that lived in Texas and eventually either moved closer to her job or got a job closer to where her family lived.
I wouldn’t want to have a commute much longer than half hour or 45 minutes. Especially, living in an area that can have bad winters.
I think that after 5 years the OP has already figured out what to do about their commute.
I’ve done a lot of field work. I covered roughly a 75 mile radius from Portland, ME. Farthest I had to drive in one day was when I had work orders in Fairfield, ME(75 miles north of Portland) and Rochester,NH (50 miles southwest of Portland) on the same day.
10 miles. Having grown up in LA, I swore I would always live within bike riding distance of work.
100 miles each way, but I did it only once a week, for two shifts on weekends in the city, then five days off back home in BFE (AKA Kansas). Did that for five years.
In New Orleans, I walked to work every day, which took 30 minutes each way, which might be my longest daily commute timewise.
