stevechow said:my cadence is around 90-100rpm most of the time and going at 30-35kmh most of the time. so how do i go faster from here. my heart rate is at 90% plus most of the journey. i cycled like i trained, 20minutes then rest 5minutes. i am using a lot of cadence using the highest gear when i climbed.
so please give me suggestions how to move on from here to go faster and stronger.
Cheers,

Do similar to what you posted:
3 sets of 20 minutes with a rest period inbetween. Start off with 2 intervals and take if from there. There's no hard and fast rule. Doing these properly is a significant effort, so expect to be tired and sore afterwards.
Intervals like these will work great for events upto a few hours - so there's really not a whole need to give up a session like this (based on raising your threshold to give more sustainable power and therefore speed) for a ride where you're twiddling smaller gears in the belief that you're getting the miles in and still doing some good... where you're actually just training your butt to sit in the saddle.
90rpm is fine - although you could try a bit lower or higher and see what works best.
For the hills, I naturally find that my pedaling cadence goes a bit lower - between 75 to 80 rpm. Same with strong headwinds.
The next time you ride a 40km timetrial, dial the effort back a tiny bit and aim to ride at that pace for about the first 30 minutes and then see if you can up the effort a little. You should know by then if it's possible. If not then just continue with the same pace to the finish. Idealy, you'd get around the course without taking rest breaks. If you can't the at your next event dial the effort back slightly further still.
