Obstacle Race Training

Amphibirun will have high and low obstacles with some distance to run in between. The obstacles are arranged so that those which exercise the same groups of muscles are separated from one another. None of the obstacles are compulsory, we will encourage but not force you to try every obstacle, however if there is something that you feel unable to do, then you can simply walk around, the choice is yours. To help ensure we have a 100% finish rate we have designed a tailor made training plan which you can view by following the below link.
