Richmond Park clockwise loop Glorious warm evening so a quick spin round the park. Started off gently, feeling a bit jaded after two days of commuting in and out, and missing the rucksack on my back (not a bad thing!). Finished well: quite quick but steady.
New highest average speed: 32.0kph, up from two 31.9kph circuits. Really dependent on how the traffic lights treat you. No drafting anything at all this time though.
Richmond Park - FAST!!! What a difference aero bars make! Just had the bike serviced and bought a pair of budget aero bars. My previous fastest time for the park loop was 52:44; this was 3:08 quicker at 49:36. Average speed was 1.7kph higher at 31.6kph.
I reckon they add at least 10%, save 10-15sec/km when you're using them. And this is without them in ideal position yet. I'm certainly going to move them forwards about 3-5cm. I'm only sorry I didn't buy them earlier… Still, two more sprint tris to do this spring, so hopefully I'll see the benefit then.
