Adequate training ensures that come race day you are prepared physically for the challenge. Smart and adequate training improves your chance of finishing and achieving a time goal.
But there is never a guarantee.
When following a training plan I have either made my own or taken the advice of others. I undertake a variety of workouts with ‘comfortable running’ as my base, and have committed to a stretching and core exercise routine (which includes lunges, press-ups, sit-ups and squats).
You will always spend more time and effort training than racing so it is important that both are rewarding processes.
I have learnt the most from all the miles and minutes I have run in preparation for races. They may be subtle lessons at times but if you remain conscious of every run it will give you valuable feedback for the next one.
