<p>A few of us are off to Glentress next week for the first time and I am a bit concerned about the black route. I&#8217;m not particularly fit and carrying a long term ankle injury but I love the descents. I don&#8217;t think we will have time or I will have the ability to ride both with everything else that is planned.</p> <p>Which is the best of the two for smiles per mile?</p>
