Ok, I'm 40 but only 1 year into road riding. At pretty much all my distances I can ride an average of 18-19mph, with the exception of 100k's where 17-18mph is the norm. I've ridden several 30k's at 19.8mph - pushing hard all the way.
Next years goal is to average 20-22mph regularly up to 50k, and try for 24mph on th 30k.
Right now I'm finding it tricky to get to 20mph average, it really is a teeth clenching thrash over a short (30k) distance.
I'm lactic threshold training at the moment before I lapse into Z2 distance training October to Feb, back on the LTR March and then look for MTB events pre-July, road sportives after July.
Any tips to get me faster (other than the standard lose weight/get aero etc)? Or am I doing the right thing and just need to take the time?
