Explanation: In grammar, tense is a category that expresses time reference with reference to the moment of speaking. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns. In English, tenses include past, present and future. When writing we need to make sure that be consistent in the use of tense. In the given extract all the information is in present (we have, we run, etc) except for the phrase "We also had a 20 metre pool" which is in past, it should be "We also have a 20 metre pool."
