I live in a big city.. no long opend road here. Intersections every 3 km.
Is a trainer necessary for time trial training? or i can build my strength by weight training & running?

ps. i have opportunity to ride in an open 10 km. road once in every two weeks

Thank you very much guys

I’d recommend a trainer or find a section of road you could ride as a loop without needing to stop if you want to improve.

It’s all about specificity; being comfortable racing full gas on the TT bike and regular training sessions designed to raise your FTP (Functional Threshold Power - Wattage you can sustain for an hour). This is best done in longer intervals such as the standard 2 * 20 minutes 95-105% FTP and a minute or two rest between.

As above, a trainer would be useful here. If you can leave the city limits on weekends, do that. You can do without a trainer if you find a place that let's you train the way you race.

I use my trainer mostly during the winter and found it really helped me get comfortable on my bike and get used to the fit at a lot of different cadences. It's also nice to be able to throw a pair of shorts on and jump on the bike without having to worry about dressing for the weather, fighting traffic and looking for that one piece of road that will let you get a decent workout in. I'd recommend one if you are tight on routes and have a bit of extra cash.

Thank you very much
I've started looking for a good one now....

Is it possible to use our trainer to create electricity power?
I DO BELIEVE some has invented such trainer a couple years ago using the spinning to create electricity power and save it in a battery.. I think it was in some international bicycle show in 2010 or something..
That would be sooooo coooollll :-)

It wouldn't be hard to generate electricity on a trainer but what would you do with it? Reverse meter, store it in a battery, generate hydrogen gas? That is really the difficult part. Unless you have a bunch of cash or want a fun project I would stick with your basic trainer.

Don't know what the scene is like up north, but around here there is a plethora of used trainers on craigslist. Also consider taking a spin class. I highly recommend it.
