You won't be expending that many calories so your concern shouldn't be to stay as topped up as possible, but having enough to comfortably avoid bonking.
All of this. My only other piece of advice is to stop at every aid station, even if it's just 30-60 seconds. Ask yourself if you're feeling okay. Ask yourself if the pace is good. Drink water. get a bite to eat. Get back on the bike.
If you've never ridden 41 miles before then literally whatever time you get will be your personal best. So don't overdo it only to crack at the 35-mile mark.
