Everyone is different.
You may want to become better, faster, with a fully bespoke progressive training programme geared to your chosen race(s) that builds a closer personal relationship with your coach. You may want your own individual training programme but with less coach interaction. Perhaps a standard month-to-month training plan best suits your lifestyle and needs. Your training programme needs to take into account such factors as your ability, goals, work life and family life, which will all impact the type of training programme you choose.
