Your base fitness will get you through. I'd focus on doing tempo type bike sessions, so not super high intensity but do 20-30 minute intervals at tempo, so approx 30-35 bpm below your max heart rate, and do 2 or 3 per session with ten minutes easy in between. They work well to build endurance, which is what you probably need to focus on.
