Tempted to increase your mileage?
=============================
If you have consolidated your training volume at a particular level, and you've been there for a few weeks or even months, it might be time to add some more to your workload. Here are some considerations when you have that conversation with yourself, with your training partners or with your coach:
1. Are you racing goals changing? If so, if you are racing further, you might feel as though additional miles/kms will be of benefit. This could help your overall aerobic base.
2. Additional miles should be included carefully. Make the increments sensible and include easy/easier miles before turning the extra into hard miles/kms. Using easy morning runs on a double-day, or doing gentle off-road/sports pitches miles would help the adjustment.
3. If your workload is challenging you, it is common to feel more tired than you used to feel on lower volume. Be ready for this but remember that your body takes time to adapt and to adjust before it feels comfortable. Once the additional stress has been accommodated you will feel the benefit and begin to make progress. This won't happen immediately, so don't lose heart.
4. A graded progression from week to week or month to month can not carry on indefinitely. We must build up, reach a peak, and then taper in order to feel the benefits of the heightened workload. Ultimately, whilst some improved fitness will be seen throughout the progressive training programme, the athlete's true fitness will typically reveal itself once the taper has taken place - the taper being the period where we allow the body to recover, recharge the batteries, conduct confirmatory short/sharp sessions that give us confidence before proving our form in the target race.
5. We only learn about our capacity for increased volume by trying it out. Some runners thrive on more, some on less. The litmus test is whether you can perform successful sessions when you are at each successive level. Therefore, if your hard sessions fail when you are at 100 mpw (for e.g) and they continue to fail, consider that you are too fatigued and drop the mileage. Don't do too much that your key sessions become void, too much that you invite illness, or too much that you invite injury.
6. Increasing your overall volume first should then allow you to increase the weight of effort in your long run or your big track sessions. Ideally, your long run should be a small proportion of your week. If you are only doing 50 mpw, a 25-mile run would be 50% of your work and could potentially invite injury. If you are already up to 100mpw, a 25-mile only represents 25% of your workload; your conditioning will be so much better. Aim to keep your long run at about 20-25% of overall weekly training, or lower if you can.
7. Don't do more miles for the sake of it and don't bury yourself just because you've seen your training partners do it. This is an individual pursuit and one size really doesn't fit all.
8. A weekly increment of 5-10% tends to be fine but if you've done 6 months at 50mpw, then had a week at 25, your body will tolerate going straight back to 50. So, use common sense.
If you really aren't sure, just ask. Many of us have lots of experience and can give good pointers if doubts creep in. Have fun and let us know how you're getting on!!
