I'm committed to ride a 95 km race next summer. It's advertised as a MTB race, but it's a very easy track (I'm told). Mostly gravel, some real roads, perhaps 5 km of track (not single-track).
At first I was thinking I need to get a MTB, but when I started looking into that I realized my hybrid commuter might suffice. So now I turn to the collective wisdom of BF:
Will my Scott Metrix 20 be good to go for this thing? I'm guessing I need new wheels, or at least new tyres, since the current setup is very road-ish (albeit with a rack and basket

).
What do you all think?
TIA
