Cycling

Today is the 2nd time i went cycling with my friends. Thanks to K2 to invite me to join him cycling. And thanks to Odin on keep on encourage me while we are cycling.
I'm kinda afraid to touch bicycle at first because i've injured my back few years back and it's not fully recover yet. I can't carry heavy things and bend my back too long. Besides, K2 is too extreme to me, the can go off-road and cycle for quite far.. Furthermore, my bike is outdated and rusted. I need to buy a new one if i really wanted to join them. My current bike setting is totally out of position. I have to reset the position in order to have a comfort position while riding.
After my 1st attempt with Odin, I'm quite happy as i realise that i can cycle, eventhough it is only a 7km journey. My butt hurts but my back is ok.. Kinda happy to know that i can cycle back. It's a good exercise.. I sweat a lot and it feel fresh after that.. :)
We went to bike shop in SP, Butterworth and Alma for shopping the next day. Bought a pants and glove and also listen to the advice on which bike is suitable for me. I'm kinda surprise that i actually need a S size bike for my own. My leg is too short to go for M size, else it will be tiring while i cycle.
Today, K2 and Odin came to my house and ride with me. I'm kinda paisay to them as i'm the slowest, and i'm too beginner to them. They keep on waiting for me... :(
My back pain started back while we are still half way. I just keep quiet and continue to journey as i hope i can train up my back.
Although my back is pain for the 2nd attempt, I still will continue with it if my back allow me to do so.
