I do a similar commute, though I try and do there and back on the same day twice, maybe 3 times per week. Anyway, here’s what works for me:
1 banana and an espresso before I leave the house in the morning. I have a gel in my pocket for emergency energy lows but never use it.
Big bowl of porridge after I’ve showered at work.
Maybe another banana or an apple mid morning.
Lunch is a hot bowl of something I make with brown rice, tomatoes and turkey mince (amongst other things).
Maybe an apple mid afternoon.
Small sarny or similar before I leave to go home.
Normal dinner when I get home, low carb, high protein.

But. I am often hungry and kind of accept that. I also often need a strong coffee to get through the morning, again, that’s fine.

2-3 hour sleep at your desk, plenty of tea and cake before you scuttle back off home.

Are you getting PLENTY of water in? Like, 2-3 litres minimum per day?

I found myself really flagging when I was getting dehydrated

I’m the same – off road commute 15miles each way soon makes you tired whereas 50-100 miles at the weekend doesn’t take its toll so much.

I guess it’s wrapping it around a working day that the issue. And often not taxing enough to be a training ride that makes the endorphins flow.

I don’t do anything as far but for me I have to have porridge before leaving. Impressed with your commitment. A commute like that would be A twice a week max for me!

I find if I cycle to work and back every week day I don’t want to ride on a weekend so I limit myself. Usually do 3 or 4 days depending on the weather.

It usually hits me around Friday. I just try to eat as much food as possible (rice and chicken meals, pasta etc) . No scientific basis behind it, just make sure I’m fuelled.

My friend uses the zero tablets you add to water, he says they make a difference to him.

If I was doing a 2 hour ride I’d have food with me. The best one I’ve seen is the home made cereal bars with peanut butter/chocolate. Mix it all together, slice it and freeze it. I’m sure someone will have a good recipe. Take some of that with you in a morning.

Might not be the cycle or nutrition at all.
Not being in any way a morning person, i’d be no use to anyone if I tried to do the above.

I did 50 miles there and Mon/wed/fri and was always hungry and to be honest too knackered to work effectively in the afternoons. I did it for a year and now drive half way dump the car and cycle the rest. Works for me as now have the energy to work and ride the mtb at the weekend.

I do half of what you’re planning to do and I’m spent by Friday, albeit I do it every day.

I drive to Orpington then cycle in from there, riding 16 or so miles to work through London. Because of the traffic, some of it is quite high intensity, some parts less so. Not much climbing except for round Chislehurst.

I have a coffee in the car on the way to the car park, then have breakfast of either eggs or a roll of some sort when I get in. Big lunch (normally cooked from our canteen) then a snack before I leave. Then proper meal when I get in. Its a lot of food, but I’m still losing weight and I’m still constantly hungry. I just figure its ok to be hungry when I’m not riding, but will make sure I’m fully fueled from about 4pm on so that I’ve got the energy to ride home. I’m toast at the weekends though – tend to leave the bike well alone until Monday morning.

My hamstrings are SUPER tight all the time – might take the advice above and go for a walk at lunch

70km round trip here. The morning leg is done on no breakfast and water only. I eat when I get into work, and have a lot for lunch. I generally feel fine in the mornings, but I do drink a coffee or two (that’s normal even if I’m not riding). The afternoons however can be a mixed bag. I’ve had the odd occasion where I’ve experienced an extreme blood sugar drop late in the afternoon (bonking at your desk isn’t very nice!), which necessitates emergency eating before embarking on the ride home. Every now and again it happens on the bike, so I carry an emergency gel or two for that eventuality (although it’s still hellish).

Try and get out of your chair and do some stretching. Sitting down all day after doing a ride makes my legs seize up so I try to go for a short walk at various points in the day. And do a decent stretching session when you get home.

I do a 50 mile commute quite regularly (2-3 times a week), in fact all 5 days last week but one 🙁

I have an espresso and bowl of porridge or Wheatabix before I set-off, apples and fruit during the morning, butty for lunch and a banana before I set off home. Then a normal meal at home for tea.

That seems to do me OK, one thing I have noticed is that just knocking the pace down slightly helps you get through the week a bit better.

I also carry an emergency gel, very rarely use it, but If I have been working late and it’s been a few hours since lunch, that’s when I need it @ about halfway home 🙁

The getting up at 5am does as much damage as the riding IMHO 🙄

Yeah. You can do a long ride without eating much so long as it’s a slow pace. For fasted rides, you don’t want to go above zone 2.

What is the terrain like? Flat, rolling, hilly?

I would have a bowl of muesli or porridge (preferably low sugar) before you leave, and stick a banana in your jersey. Then have something more protein-y when you get to the office. Maybe a couple of eggs, or if you don’t have a microwave, a glass or milk, or greek yogurt.
