Andy Vernon; GB Olympic athlete and European Athletics Championship medallist has written us a 12 week Half Marathon plan. The plan is split into 4 phases, and is aimed at all abilities, including those who haven’t done much running previously.

If you’d like a personalised training program written by Andy then email coach@runthrough.co.uk for details on pricing. 

Whilst following this training program it is important to understand a few rules to get the most out of the training you put in.

  1. Any day that is just listed as a run for x amount of time is simply a very easy and light run. You should be able to hold a good conversation while doing your easy run and you should always be able to run a bit further if you had to. This type of run is often referred to as ‘junk mileage’ but when training, no mile is a junk mile. Every mile you run serves a purpose and will help you improve endurance and strength while also helping you recover for the next hard day.
  1. The warm ups and warm downs should be treated exactly like the steady easy running days. They are simply to get the body moving and warmed up prior to starting something faster.
  1. There should be a considerable change in pace between your warm ups/downs, recoveries and easy running and anything faster. If you can’t pick the pace up for a threshold run or a session rep then you are doing the easy running too fast. It is extremely important that you have a change in pace when required. A one-minute rep should be faster than a five-minute rep. If you start doing everything at the same pace, you will find it very hard to get faster.
  1. Anything listed as @ TP means at threshold pace. This is the training designed to increase your aerobic capacity and improve your lactic curve. Anything with this should be done at 80-85% of you maximal effort; you should be able to talk in 3-4 words at a time. If in doubt it’s always better to go slightly slower than too fast but make sure it is faster than your easy running.
  1. Remember that this is a guide and not gospel. If you need to change days around, take an extra day off or two due to tiredness, fatigue or injury than do so. If you need to shorten a run or would like to lengthen a run as you go a long then please do but don’t stray too far from the program if you don’t have to. It has been put together to steadily increase mileage and intensity in a structured way.
  1. Good luck in achieving your goals and enjoy getting fit.

Phase 1 – Introduction to Running

If you currently do none or very little running then you can’t jump in at the deep end. Running is very strenuous on the muscles, bones and joints and doing too much too quickly during the initial 4 weeks will probably end your marathon campaign early through injury. You need to condition your body to withstand the stresses and strains it will be put under during training. Thankfully though, the human body is pretty resilient and very adaptable and by following these guidelines you should feel ready to progress on to the next phase comfortably.

Phase 2 – Building Aerobic Capacity

Aerobic Capacity put simply is the amount of oxygen the body can utilise per minute during exercise. The more oxygen your body can breathe in and send to the working muscles, the more efficient you will become allowing your muscles to work longer before fatiguing. This phase is fairly simple, you lengthen your runs and you work at your ‘aerobic threshold’ twice a week but the science behind it is not so simple. See below for more info.

phase-2

What is aerobic threshold? I hear you ask. Well I’ll tell you. Aerobic threshold (sometimes called lactic threshold or tempo running) is a given pace or effort that one can exercise at (in our case run) where the body is at its limit (or threshold) before the onset of lactic acid occurs. Typically this is around 80%-85% of your maximal heart rate and is completely individual as every ones physiology is different. There is a fine line between running at your aerobic threshold and being slightly over. If you’re unsure it’s always better to play it safe and run a bit slower than go too fast and blow up. It’s actually very important that you don’t go too fast as this is a very specific type of training with an outcome that will only work if its done correctly. The idea of it is to increase the bodies’ capacity to working at this effort in order to run further distances, at faster speeds but still staying under that magic threshold effort where you don’t build up the dreaded lactic acid. This will ultimately be just faster than the pace you should try to run your marathon at.

Phase 3 – Half Marathon Training

Now that we have a pretty big aerobic base to work from we can now start to implement marathon specific training. This will be a mixture of steady running, sessions and long runs building up in either intensity or volume week on week to prepare your body to withstand 13.1 miles. It will be key to listen to your body during this phase as it’s the hardest and longest phase of the program. If something starts hurting and you have to miss a day or change things round a bit then by all means do it. Remember that this is just a guide and is not gospel. Even missing a whole week won’t make much difference over a 12 week period but don’t make the mistake of trying to make the training back up if you do have to miss some training though.

Phase 4 – Taper

This is the best part of the schedule, this is where we start getting the body ready to race. In this phase the training will slowly start to trickle down and rest up so you’re ready to hit the race hard.
