Ah thanks for the tips.
Actually had quite a good ride at the weekend. Managed an average of 19.5mph over 50 miles, robbed of hitting 20 because I loaded the wrong route and chose an old one that has a few miles of gravel cycle path. That and 10 miles of headwind to finish. Punctures at 25 miles and 49, lol.
But the main thing was that I was able to spend the vast majority of time in the extensions. And based on the speed I managed I’ve put a conservative estimate of 1:15 in for the 25. And will aim for 1:10 if I can.
