My daily commute is about 13 miles each way. North Queensferry to the centre of Edinburgh. If I use the cycle path into Edinburgh, after crossing the Forth Road Bridge, it takes me about 56-58 mins, depending on traffic when in town.

If I take the dual carriageway after I cross the bridge the distance is less than a mile shorter, but I cut my time down to about 45-48 mins!. A combination of fear and drafting from cars.

The cycle path involves changing direction a lot and much stopping and starting, the dual carriageway, fear of dismemberment.

If I get rid of my "lovehandles" I'm sure I can go a bit quicker.
