After all that training, I've finally managed to finish my round Kallang route in under 50 minutes. It is only a small improvement as it'll still take more than 2.5hrs for me to finish the Round Ubin Kayak Race at this rate, but at least I'll come in under 3hrs.
To have any hope of winning anything at all, I need to be able to complete the race below 2 hours and 30 minutes. I'll strive towards that timing. That'll be my target!!!
