You trained according to a set plan to achieve a specific goal time. That means your training conditioned your body and mind to sustain a certain level of effort and intensity over the race distance.
However, it is easy to get caught up in the excitement of the mass start and go out too fast with the a faster bunch. This is a recipe for disaster because a harder effort in the first half of a race will sap your energy reserves for the remaining kilometres.
However, it is vital to find the right group and settle in as early as possible, especially if it is windy. Starting in a seeded group is ideal as they are generally more organised and riding in bigger bunches creates the slipstream effect, which conserves energy. There will also be more riders to spread the workload as they take turns ‘pulling’ the bunch along in front – do your best to contribute to this collaborative effort if you can.
If you lose the bunch, slow down and wait for the next group to pass, until you latch onto one that is travelling at your ideal pace. Don’t try to ride solo for too long.
Further down the field you’ll find riders who are competing as a personal challenge or for charity. These riders will normally start in an unseeded group, which is far less organised. As such, it’ll be harder to find an organised bunch. Do what you can to find and stick in a group.
Whatever approach you take or position you find yourself in, stick to your pacing plan from the first kilometre to have the best chance of achieving your goal time. Only if you’re feeling good in the closing stages of the race should you up the pace.
