Opening Weekend – 14th April

Morning All, a reminder that we will be opening for the 2018 season at 8:30am on Saturday 14th April. After the winter weather the site is damp, and at the date of writing there is still a large pool of water on the entrance road, so do take care when driving in. We will review the condition of the run track once it has dried out, but it looked okay prior to the Easter rains.
See you at the lake!

2017 season now closing at midday Sunday October 8th

Morning All

As we are seeing very few of you braving the waters now we have decided that tomorrow, 8th October, will be our final day for this season.

The generator also gave up this morning so no bacon rolls, but campervan is there providing hot drinks this weekend. Without power for hot drinks and heating we are not comfortable allowing swimming to continue in water that is getting colder by the week, so tomorrow will be our last day for 2017.

Thank you all for such a busy season, and to the Trifarm team for being brilliant as always. We will reopen on April 14th.

The 2017 Season – Closing soon!

Trifarm – Only 12 swimming days left.


This week is the last week of evening swimming at Trifarm. We open at 5pm, but light will be gone around 6:45pm so try and get here early. Friday 29/9 is the last weekday swim for the year.


We are then open on the weekends 8:30am-Midday, NOT 2pm. Your last day for swimming will be Saturday 21st October.


We will NOT BE OPEN on 22, 28 & 29 October.


We aim to reopen for 2018 on 14th April.

Swimathon – Sat 9th September – Midday lake close

Trifarm is pleased to be one of the venues for the Open Water Swimathon this year. The swim is taking place between noon and 3pm on Saturday. As a result the lake will be closed from midday to allow the Swimathon to take place and laps to be accurately counted. The run track and rest of the facilities will still be open for those wishing to train or eat cake after a morning swim.

September/October opening times

A heads up as we head into September and have to face the reality that the sun will start defeating us in the evening as the month progresses. By the end of the month sunset will be around 6:30pm, and we anticipate that Sept 29th will be our last weekday swim. Our closing time will be dictated by visibility across the lake. We should just about manage 8pm this week, but from next week we might be losing 15-20 mins a week as the month progresses. Upto the middle of the month we would recommend being here before 7pm to ensure a reasonable dip, and maybe aim for 6pm in the second half of the month.

At weekends we propose staying open until 2pm whilst numbers support that, the weekend just gone was very busy. If and when numbers start to diminish we may review this.

We plan on opening over the weekends in October, and are likely to be open for swimming 8:30-midday based on the numbers we have seen before.

See you at the lake.

29th July Race Trifarm Triple Crown Race Details

Only a few days to go until we see you for our second Triple Crown Race

The lake has cooled over recent days and so betting is the water will be below 22 degrees, and so wetsuits are likely to be allowed.  This will only be finalised once the final temperature check has been done around 1 hour before the race.

You can view the 18k bike route for Saturday’s race here, to download a gpx click on the second icon down on the right hand side of the justgoride page;
