Food Glorious Food Part 2: What does it all mean!?

So, I've bonked on my ride, puked up the next day and nursed myself through a power-headache, all for the love of cycling. So why did it happen and how can I stop it happening again? Well, the Internet is a wonderful place, and there are plenty of resources for folks like me who have never real thought about this stuff before. Some are more authoritative and scientific; others are discussions on forums, where folks like me have asked these questions before. That's where I started. Here's what I learned.

Any physical activity burns calories. We all know that, right, but what exactly does it mean? Well, it means that if you burn more calories you need to eat more. Not rocket science, no, but what the heck should we eat and when? Is it okay to burn 1500 calories on Saturday then binge drink your way through the week to make up the loss? See, not so silly to ask these questions after all...

Now before I get all geeky about this I just want to say one more thing. The food/miles issue has never ever come up before on social rides. On a ride with friends I know there will be cafe stops (at least one) and then there are the rest stops en route -- the ones at the tops and bottoms of hills, where we all regroup, providing ample time for a refuel if needed. I have no problem feeding myself on rides like these; in fact the frequent snack stops are my favourite parts of the ride. No, the problem is when I'm on my own, because then I get it in my head there's no time to stop, no point in stopping. Maybe it's a security thing? I don't know. Whatever the reason, when I'm on my own I m on a mission and that's the end of it. So the other part of this lesson is educating myself about ways to eat that don't involved lengthy, social chat stops -- the lesson for those rides is learning about food as fuel.

So, what do we need when there's no time for a cake and butty stop but you still have many miles ahead of you?

Well, the first thing is you need to know how much fuel you need to keep going. To figure this out you need to find a way to log the mileage you're doing and perform the necessary calculations for your age, height, and weight. If you have a GPS and use this to track your rides, the chances are you have this information to hand already. Use it. Study it. Try and figure out a rough guestimate for the different types of rides you do, considering terrain, distance, speed, etc. All those things affect how much fuel you need. When you have this you should end up with a figure for the number of calories you need per hour of activity. So far so good. For me I'm looking at about 300 calories per hour on a "regular" ride. Anything above "normal" levels of activity (races, etc.) I will need more than this.

Second, figure out what you can actually manage to eat while riding. It's one thing sitting down for a butty and swilling it all down with a cup of tea, but if you're pushing yourself hard you need to embrace food as fuel and keep it simple. There are a tonne of products out there to help with this: gels, energy bars (usually dried fruit mixtures, some with oats, etc.) and also energy drinks. When you start looking at these the wide range and different definitions will blow your mind. I haven't figured out what I like yet, so have bought a stack of different products and will just try them out as a ride. Some I'll like, some I won't. I'm hoping that I end up finding one that I can make really cheaply for myself. The products don't need to be specialist sport bars either. Products like Nakd fruit bars and others are available from most whole food shops. Basically what you want are slow release carbs, from dried fruit, oats, etc., and it also helps to have a stash of simple sugars for a speedy fuel injection; jelly babies are as good as a fancy energy gel -- think of this as your get out of jail food.

Then you do need to actually keep track of what you eat, not just during the ride but before and after. I've started doing this because I was worried I wasn't eating enough. My weight was stable but my body fat % was increasing, which suggested that maybe I was in "starvation mode" and my body was storing fat to get me through periods of exertion because I couldn't be relied upon to feed myself properly. I've been using My Fitness Pal, on the recommendation of a Breeze participant, for a couple of weeks now, and it makes pretty interesting reading. Basically, I haven't been eating enough for the riding I'm doing, so now I have a chance to rectify that, which will make me a stronger, healthier, happier rider. Plus I to get to eat more -- marvellous! Saying that, *when* I eat more needs to change too. I still don't eat enough on ride days. Refuelling after is important, and one way to do this is to include a protein shake of some sort into your day. Again, there are a tonne of products out there, some of which are very much aimed at blokes, so lots of focus on muscle gain, others of which are for muscle repair. The products I'm trying (again, trial and error is the way forward) are to assist repair and contain a balance of carbs and protein plus some other vitamins and minerals. I've been trying a few products out after all my recent rides and they have really helped me up my calorie intake to a level that matches my activity level.

So is there any more to say on this? Well, yes, actually there is! But that's enough for now... More to follow.
