5w per kg seems to be a good number and really how long should i be able to hold this power, obviously a longer amount of time is better but i dont think i can hold 10 minutes, so what workouts would i do to increase this, should i do 6w per kg for 3 minutes or 4w per kg for 20 minutes ??
5 W/kg sounds like a great number, but then again so does 6 or 8! Rather than just aiming for what might be a random number, you should schedule your training goals to something that is correct for you and realistic. Goals like this are SMART. Specific, measurable, adjustable, realistic and time based. In this context the realistic is the most important -- there's little point in setting a goal of X W/kg if all you can currently do is 0.5X W/kg.
As Steve points out, it's very much dependent on what goals you're trying to achieve. Are you a 1-km track TT rider, a roadie, a track pursuiter, etc?
Performing longer intervals (e.g., 20-mins) at a more moderate intensity (compared with going all-out for 3-mins) will help with your TTpower/sustained power, but these should be based on what you can currently do over a similar duration (rather than an arbitrary number).
Additionally, if you perform a MAP test (see http://www.cyclingnews.com/fitness/?id=powerstern) and a couple days later perform a longer TT test you can ascertain where your relative strengths and weaknesses are -- for e.g., if you race endurance events (e.g., RR/TT/MTB) and find that ratio of TTpower to MAP is low, then you need to work on increasing that ratio (use longer intervals), on the other hand if the ratio is high then you're being limited by your MAP/VO2max and will need to improve that with shorter intervals (e.g., 4-mins).
If you would like a file that shows you what power to aim for, for a MAP test please give me a shout and i'll email it to you.
