Cramps may not sound like a big deal, but studies have shown that they affect one in two runners. I too have suffered from cramps numerous times while running.
The exact cause of muscle cramps is unclear, but it is often attributed to dehydration, or the lack of certain electrolytes such as sodium.
I would also add premature fatigue of muscles to the list. This happens when we overestimate our body's threshold and push excessively hard during training or competition.
That is why cramps often occur at the point of maximum intensity or during extreme fatigue in the latter stages of a marathon.
Researchers found that triathletes suffer from cramps when they push themselves at a higher intensity than their bodies are used to.
RUN WITH MOK - WEEK 2
This will be a more challenging fartlek session using a pyramid training system.
After a 10-15 minute jog, run a fartlek of 3min - 2min - 1min - 2min - 3min - 2min - 1min, each with the same recovery period. This means running hard for three minutes, easy for three, then hard for two and easy for two minutes. Continue until you complete the session as above.
For each interval, try to start slow and run faster towards the end. Wrap this up with a cool-down run for 10 minutes
Having completed 6km at race pace last week, go for 8km this time. It is important to evaluate how you felt during last week's run. Do you think you can complete the race at that pace? If not, discuss with the pacers and consider slowing down for today's run.
You can join running group Running Department, who run on Wednesdays at 7pm at UOB Plaza.
This is an optional run for those who are fitter or keen to train more. Do a 30-minute run at an easy effort. You may replace this with an easy 30-minute swim or cycle. This active recovery will help your body get ready for Saturday's long run.
The weekly long run is the bread and butter of your training programme.
This week you will cover 14km. Remember to maintain an easy effort throughout the run.
You can do this with ST Run's official pacers, Team FatBird, who are conducting a 12km training run at Punggol Promenade (Tebing Lane) at 7am. This is open to all 18.45km participants.
Training effort description
Easy/long run: You should be able to hold a conversation comfortably during the run.
Moderate (race pace) run: You should be able to speak in phrases but not in full sentences.
Hard (fast) run: During these intervals, you should only be able to speak in sporadic words.
If you often suffer from cramps, the best bet would be to start the race more conservatively and slowly build up your pace, in order to avoid over-taxing your muscles.
Stitches are another common ailment affecting runners, with a sharp pain that strikes just below the ribs. I have not been spared from this problem either.
As with cramps, it is still unclear what exactly causes a stitch. Some suggest that it may be due to a spasm of the diaphragm, while others say it is due to the stress on the structures that keep our intestines and organs in place when we run.
A study by the University of Newcastle in Australia found that 60 per cent of 965 athletes surveyed thought stitches were caused by eating or drinking just before exercise - in particular, consuming fruits, juices, dairy products and food high in fat and sugar.
Other factors include exercising in cold conditions and a lack of warm-up.
In any case, despite the inconclusive evidence on cause and prevention, I recommend the following preventive measures.
First, make sure there is sufficient time between your pre-run snack and training. Personally, I have a snack bar 45 minutes before a training run.
Time running out to sign up for the ST Run

Second, warm up. This can be a brisk walk, or an easy jog for 5-10 minutes.
Finally, regulate your breathing. Breathe once every 3-4 steps during an easy run, and once every 1-2 steps during a fast run.
If the stitch still strikes, do not panic. Try this remedy which works for me occasionally: Exhale when the foot on the opposite side of the stitch hits the ground. For instance, if your stitch is on the left side, breathe out when your right foot hits the ground.
If the pain still persists, stop running and rest until it subsides. As the saying goes, to rest is to walk further.
