Most importantly, you'll need to try and bundle up those nerves and excitement to prevent yourself from going out too hard during your training rides leading up to the race. My suggestion would be to try and get in as many rides as possible during the week, but instead of making them short, high intensive interval sessions, rather focus on keeping in an aerobic zone and go for distance. You can do this for up to 4 or 5 rides a week, and throwing in 1 or 2 short, high intensity rides (like hill repeats for example) on those days you can't make a longer ride. Each week, try add on 10% to your total ride time, but just make sure to taper off the week of your race, doing only 2 - 3 short rides with some high cadence sprints to keep the legs ticking over leading into your stage race... Hope this helps, and good luck for the race! Feel free to drop me a mail (email@example.com) or DM if you'd like any further help or advice!
