Just cycle slower for a day or two.
Set off 10 minutes earlier and play by the following rules.
1) You are not allowed to overtake another cyclist. Ever. You will either get stuck behind someone slow and have a nice relaxing ride, or behind someone quick but you will not use as much energy because you are drafting them with no intention of racing.
2) No filtering past stationary/slow traffic. Will help with your speed discipline.
