+      The Functional Threshold Power (FTP) is the power you can hold
+      for an hour all out. If you haven't done a full out hour, you
+      can also take a full out 20 minutes effort and take 95% of it.
+    </p>
+    <p>
+      If you do not row with a power meter on the water, the FTP on
+      water is irrelevant. If you do not know your 20 minute or full
+      hour full out power value on the water, take 85% of your indoor
+      rowing value.
