Monthly 1.5K swim TT

Did my first 1.5K swim TT this AM for the 2018 season. My time was 31:16 which is 1:54/100 yds...pretty slow, even for me.   I really lost it in the final 500 meters. Once your arms turn to lead, there is no going back! Looking back at my times from the spring, 2017, it appears like my best 1.5K was 30:10 or 1:50/100 yds, a minute faster than today and 3 sec faster per 100. That is a good goal for now, but I would like to get under 30 minutes and that seems possible.
