If you're working towards a marathon and aiming for a time of around four hours check out this 18-week training plan

Background

» Club member, runs regularly and competes in all local events including cross country and road races ranging from 5km to half-marathon
» Trains five to six times per week and runs for 60-70min on a Sunday
» Been running for three years or longer
» Aims for PBs, however enjoyment and socialisation play a major role in involvement as well as team events

Overview

» Targeting to complete the marathon distance in around 3hr 45min - 4hr 15min
» Aiming to run the whole distance
» Training with a group of 12 or so similar ability runners on club nights and with around 2-3 training partners also targeting the same marathon as you on other nights

Training

» Most runs are based on ‘time-on-feet’ with sessions at slower than marathon pace, marathon pace and half-marathon pace plus some 10km speedier runs to improve running efficiency
» When specific build-up begins (around 12 weeks prior to race) focus will be on pace judgement
» Fastest race pace target (3hr 45min) is around 8min 30sec per mile which is around 7½ miles in an hour
» There is no need to run the marathon distance in training – consistency of training will give greater benefits

Advice

» Set training goals and try to stick to them
» Wear the right footwear for your biomechanics (get professional help)
» Aches and pains will be encountered – make sure you differentiate between these and a potential injury
» If too tired or achy, don’t be afraid to miss a training day or two or even deviate from the training plan
» Try some cross-training at a gym (elliptical machine) if you feel too achy for a few days or if the winter weather becomes too dangerous
» Try varied routes and some softer surfaces in daylight hours to alleviate the stresses and strains on muscles and joints
» Keep focussed and cut down on alcohol and eat healthily. You will burn many more calories in your training – these need to be replaced correctly
» When trying to run at a pre-determined pace select a flat route as hills will play havoc with your target speed
» Look for some build-up races as part of your training. A half-marathon or longer (not a marathon) around 10-12 weeks before your marathon would be perfect, plus some 10km races to hone your speed and act as fitness tests. These also make a welcome break from the tedious training plan!
