Ultra Endurance, Audax and super-long Gravel events are becoming more and more popular, but how can you train for these massive distance events if you are limited on the time that you can train? I’ve done a couple of 200 mile rides for charity, which have also been useful for testing out some theories and practices to apply in order to maximising performance across this distance with minimal specific training towards that goal. The first time I did a ride this long, I blew up repeatedly and was wrecked for several days afterwards. The second time, I only stopped once briefly to fill bottles and grab some more food, and was able to be competitive in some E-races over the next two days. So, I thought I’d share my experience of some preparation for (and experiences during) two very different 200 mile rides and let you know which differences made one ride far better and more pleasant than the other…
In the lead up to the second ride, I hadn’t been able to get much endurance riding in due to an increase in work volume. 4 hours was the maximum time I had managed to spend on the bike, with weekly hours between 10-12 and quite a lot of work being done on the indoor trainer. Not what you’d think is ideal training for a 200 mile ride! However, maximising performance over that duration comes down to a few simple principles that can be trained for within limited weekly hours.
The primary principle to consider is Lactate threshold, LT1 specifically. The first time I did a 200 mile ride, I went too hard on the climbs that occurred in the first half of the ride. As a result, I blew up frequently, even while consuming a lot of food. It got to the point where there was no more room left for food, yet I was still starving so relied on espressos with lots of sugar to get me home. I also took over a week to recover. Next time round, I kept the intensity below what my calculated LT1 was. LT1 is the threshold at which, after crossing, your body starts to use more carbohydrates as a fuel source rather than fats. This is important since carb stores and ability to ingest carbs are limited, yet even 7kg of fat (10% BF for a 70kg person) contains ~49000 kcal! This is easily more than enough to fuel the ~8000kcal used during the ride. However, you still use some carbs - even at low intensities (for example, to fuel the brain) - hence why your cognitive functions are limited when you blow up! So, carb consumption and carb sparing are important as the rate at which you can fill up the tank, and how much you can fill it up is limited. By the end of my second 200 mile ride, I didn’t feel excessively hungry or tired (maybe that was more due to the 3:30am wake-up for the first one!) but there was muscular pain because my gearing wasn’t ideal for some of the steeper climbs. To maintain a wattage below LT1, I had to use the smallest gear (39t/28t) at very low RPM, which did result in a fair bit of neuromuscular fatigue by the end. Compact gearing is looking very inviting if I attempt that again!
Nutrition wise, I ate A LOT. For the first ride, I made the mistake of consuming all my food in solid form and drinking plain water, which equated to a lot of volume. Second time around, I consumed 400g of carbs in drink form along with x4 gels (20g CHO), x4 bars (40-45g CHO), x2 energy blocks (40g CHO), a sandwich, flapjack and can of coke. Add to that the massive bowl of porridge beforehand and it was a fair amount of food. The first part of the ride was the toughest as I set off very shortly after eating and it took a while to get that into the system. It also didn’t help that it was cold and wet. Carb drink was swigged regularly and food consumed at the rate of at least one item an hour. I did miss one feed due to tackling successive climbs and focusing on breathing more than eating, which showed come hour 6-7. The quick stop for food helped with that though and, in terms of energy levels, those were fine for the rest of the ride. It helps if you’re used to consuming a large volume of food while exercising; that’s something I’ve really worked on the last few years. You can’t just consume 100g/hour of carbs without training your gut to deal with that first!
Mentally, it was an ordeal. The first 8 hours were done entirely solo, save for the food stop at a bike shop where I knew the guy working there. I think you have to be a different breed to be able to do that day-in, day-out for events such as The Transcontinental! I had a bit of company for hours 8-9, which did help. It was also beneficial to have bibshorts with a good chamois and having enough layers of clothing that I could strip some off if need be. The bar bag space that was initially occupied with food was empty by hour 8 so I could whack my base layer and warmers in there when I no longer felt the need for them. There was quite a lot of riding out of the saddle come the end of the ride but a generous application of chamois cream had definitely helped in that department. Pressure is also an issue so choice of saddles for long-distance events should definitely be a consideration.
In terms of how to train for events of this distance, the key physiological points are: being proficient at burning fat for fuel, increasing LT1, and training the gut to deal with the nutrition requirements. The way in which you do that is primarily by increasing the amount of mitochondria you have in the muscles as well as increasing the ability to transport oxygen to them. I’ve covered this before in this article which explains the ways in which this can occur. In brief, with the correct balance of high intensity intervals and low intensity longer duration training, you can increase your fat burning capacity and therefore your LT1 too. In our plans, such as the 200 Mile Gravel Grinder, this is exactly what we focus on! So, even with a limited amount of time to train a week, it is certainly possible to train for ultra-long events, or multi-day events by being smart with how you train and clever in how you prepare.
Takeaway points
- Increase your aerobic fitness via MAP and FTP training. This will help increase your LT1
- Practice your fuelling strategy and intake in training before the event
- Know what’s coming up on your route
- Choose your equipment wisely (gearing, shorts, saddle etc)
It would be great to hear any ultra endurance stories from anyone in the SYSTM community to add to this! What went well and what was a learning experience for you?
