greetings. I'm a bit of an old bloke (43) but can still hold my own and am looking at getting back into cycling. I live in heidelberg. So don't feel rtoo bad if you want to go on with some younger riders. anyway, in terms of rides around where you are you could do worse than heading down plenty road where you can keep going for 35km to Whittlesea. Its pretty flat and there is some okay scenery past Doreen. If you want to throw in a little climbing head down Heidelberg Road until you hit Chandler highway, then go left and over the bridge. There's about 4-5 km of climbs - all be it pretty easy. Make it a little harder by coming back the same way, then going further along Heidelberg Road to Heidelberg.
