You may have heard the term ‘burning matches’ when you have been out cycling with friends or in groups. Exclamations such as ‘she burnt all her matches early on and could not hang on at the end’. But what does it mean to burn a match and how is that in any way useful when out riding? Simply put to burn a match is just a way of saying that you did a hard effort. This may be up a climb or at the end of a time trial when you have pushed yourself to the limit.
Think of it like this – At the start of a ride you have a match box full of matches. Every time you attack, push it hard over a climb or sprint past your mate, you burn one of your matches. The number of matches you have is personal to you so understanding how many you have to burn is important, especially when riding long endurance based events or when road racing.
For the riders I coach who want to win gold medals at top sportives or are doing Ironman, I teach them how to change their riding style to preserve their match box – riding smoothly with no sudden surges in power. For the racers it is different, as you need to be able to burn matches but at the correct, strategically beneficial points in a race.
Another way of thinking about this is to imagine that at the start of any ride you have your aerobic engine. Given enough fuel and ridden at the correct low intensity, a well trained rider should be able to ride all day at this intensity. Then you have your anaerobic engine which, to make it simple to understand, we will say is used for any effort above Functional Threshold Power or Threshold Heart Rate. This anaerobic engine is like a rechargeable battery pack with limited power. If you are well rested this battery pack should be fully charged for the start of a ride. Every time you go above threshold you use one or more of the batteries. Once the battery pack has lost all of its power you can’t recharge it until you stop riding and recover. You know the feeling when you have been on a hard ride or had a tough race with lots of surges in power. At some stage you have nothing left in the legs, you can’t get your heart rate up because you just can’t put in any effort.
Physiologically we are all different. We recruit different types of muscle fibre depending on our genetics, level of fitness and what type of riding we happen to do. If you are riding for endurance you want to be using your slow-twitch muscle fibres as much as possible. These fibres are great at repetitive movements and are relatively resistant to fatigue. When we push hard on the pedals we recruit our fast- twitch muscles. Fast- twitch fibres are great at producing explosive power but they fatigue quickly and deteriorate with age. This is one reason that I work on increasing cadence with many of my athletes during the winter months. Higher cadence means that you are recruiting more slow -twitch muscles and hence have more endurance.
When you light a match you are using energy quickly. Firstly, you are recruiting fast- twitch muscles – if you have not trained for explosive bursts of power you will soon find this style of riding extremely fatiguing. Secondly, you are draining glycogen from your muscles at a fast rate – this is your primary source of fuel when riding. Think of it like this – when you have 10 miles of fuel left in your car and have 12 miles to drive to the nearest fuel station do you, A – drive slowly and smoothly, or B – drive erratically constantly accelerating and braking?
When you are riding your bike it’s the same deal – the further you want to go the more efficiently you have to ride. The aim is to conserve the box of matches or the rechargeable batteries if you like to think about it that way until you need them – at the deciding points in a race, the marathon in an Ironman or the last 30km into a head wind on a long sportive.
If you are racing then you will have to burn matches to stay with the group, close down attacks or compete for a sprint finish. Knowing how many matches you have to burn is therefore crucial in order to win because you don’t want to burn them all too quickly and be left with an empty box in the closing stages of a race!
As a rider we want to understand the following
- What constitutes a match for you?
- How many matches do you have?
- When is the right time to burn a match?
- How do I increase the size of my matchbox?
In their book Training and Racing with Power Meter, Hunter Allen and Andrew Coggan define burning a match as an effort where ‘one goes over threshold power by at least 20% and holds it there for at least a minute’. Clearly the longer you ride over threshold power or heart rate the faster you will burn your matches.
The following table can be used for determining a rough estimate of how much power you need to put down to burn a match over various time horizons.
1 minute – 120%+ of Threshold Power
5 minute – 115%-120% of Threshold Power
10 minute – 110%-115% of Threshold Power
20 minute – 100%-110% Threshold Power
If you want to test to see how many matches you have as an individual rider you could perform the following test:
Warm up: 10-20 min building to Z4 Threshold
Drills: 5 min hard effort (115-120% FTP or >105% threshold heart rate or 90-100% max heart rate). 5 min recovery
Repeat 5 mins hard, 5 mins recovery until you feel intensity significantly drop then cool down. Count how many 5 minute efforts you managed and that will be the size of your match box. Say you manage 3 efforts then you know that on a ride you can do 3 very hard 1 minute efforts, or 3, 20 minute threshold efforts before your match box is empty. This is not a precise science but having a rough idea of the size of your match box will enable you to plan your riding or racing in a far more strategic way.
Individual riders will burn matches at different rates depending on their physiology. For me I know that I burn fewer matches riding 20 minute efforts at threshold than I do by sprinting 1 minute efforts – they kill me off quickly which is why I suffer when the pace of riding keeps changing quickly.
Understanding what constitutes a match for you is important to decide what type of training you need to do to become a more proficient all round rider. The great news is that we can all improve the size of our match box with focused training. The bad news is that we are all saddled with the genetics that our parents gave to us so if you are slow twitch dominant then it is very unlikely that you will ever become a sprinter and visa versa. It is one reason that you see so few ‘all round’ riders who can sprint, time trial and climb mountains. Think Eddy Merckx, Fabian Cancellara, Peter Sagan – legends for a reason! Figure out what is holding you back and feed that back into your training. You don’t get better by doing the things that you are already good at – you get better by understanding what limits your current performance and specifically training to improve it.
You know how big your match box is and you have have trained specifically to improve its size by focusing on your limiters. Next you need to know when is the right time to light a match. Think of a typical flat pro race. A breakaway forms, and is allowed to develop. With 30km to go the peloton start to get organised and the domestiques close it down and protect their sprinter. Last 2km the lead out riders take charge to make sure they get their sprinter into the right place to launch her attack. With 300m to go the sprinter kicks and charges for the line. For the domestiques the right time to burn matches is closing down the break, for the lead out riders it is with 2km to go, for the sprinters they want a full box to empty in the last 300m.
For those of you doing endurance events you need to understand the course and figure out when the right time is to burn a match. A road race with 2 big hills near the end would mean that you want to keep a few matches in the box. For those doing Ironman then you definitely want to keep your box full for the run. If you are doing any of the multi day stage races or sportives then you need to think about the whole event and make sure that you don’t empty everything on day one. Every time your power surges you drain a bit of battery life. Over 100 miles you can empty your match box very quickly!
This is all about being self aware and understanding the challenge ahead. Every time you do an event I bet you get overtaken by groups of enthusiastic riders all gunning it from the start. A lot of the time you will pass them on hill 3 or 4 as they limp home, match box empty with their tails between their (shaven) legs wondering where it all went wrong.
