you can also turn left at the bottom of russel hill and do repeats on poplar/russel hill, it's a pretty tough hill & fun to go back down
i did that a few times yesterday and i'm in pain today
i think i'm going to try the donut once it gets a little warmer, we can always try it together and if we get droped it's not a big deal, just finnish it anyways, since we're fairly both close to the start point
