The 1000 km Mark

Over the weekend, I managed to click over 1000km since I got my L's earlier this year! I know seasoned riders wouldn't say it is much, some people doing this distance in a couple of days. However, for a novice like myself it feels like I have crossed another step. I have noticed in my Log Book that of late I have been riding further and more frequently. I wonder how soon I will do my next 1000?
