FeedBurner Sending Digests of Old Posts

Quirky Bugs with Google Feedburner

Apologies to any of our subscribers who received an email yesterday with some out of date news items from the NDAC website.

This blog uses Google Feedburner to send out our news items to subscribers, however it seems to have a glitch where it very occasionally sends out random old posts!

For anyone else having the same problem, Google Feedburner are very quiet on the subject but I think I’ve found a solution on eHow.

The issue seems to occur if you make any edits to old posts.

I believe the cause of yesterday’s posting was due to the removal of some old posts on the blog. To prevent the blog sending out old posts via Feedburner, the suggestion is as follows:

  • Deactivate the FeedBurner "Email Subscription" service. Log in to your FeedBurner account. Click on the feed associated with your website from the main list. Click the "Publicize" tab, and then click "Email Subscriptions" in the left navigation pane. Scroll to the bottom of the page and click the "Deactivate" button.

  • To reactivate the email service, click the "Activate" button. FeedBurner will show only new posts from now on.

An occasion where ‘turning it off and on again’ might actually work!


triSUP Dragon Triathlon at the NDAC Chepstow

January 27, 2016

SUP Triathlon at the NDAC Chepstow May 2016
Tri SUP Triathlon Enter Online »

On Sunday the 8th May 2016, the National Diving and Activity Centre will be hosting the TriSUP Dragon.

TriSUP is an exciting new triathlon format that introduces Stand Up Paddle Boarding (SUP) in place of the traditional swim stage.

This three stage event includes a SUP course around the stunning NDAC Quarry, a Road Bike Course and a Trail Run to finish.

Event Includes

  • Event centre facilities and parking
  • Mechanical Support
  • Full Route Marking
  • Electronic Chip Timing
  • Bike / Kit Wash Station
  • SUP Board Hire
  • Web results service
  • Emergency support
  • On site catering
  • Finishers Medal & Certificate

To enter this amazing event please visit there are full details on the page as well as special offers for early bird bookings.

Who can enter?

This event is open to all and you do not need a SUP to enter. No SUP? No Problem, you can hire one from the extensive demo fleet of Red Paddle Co SUPs. Why not share the experience with your friends and enter as part of a team which includes one of our 4-8 person SUP’s for FREE!


The SUP leg of the Triathlon is set in a dramatic quarry, the high rugged walls surrounding the water will ensure flat paddling conditions; even in windy conditions.


After the SUP leg jump on your bike and head out on the local roads of the Wye Valley for the bike leg. After an initial challenging climb up to the ridge of hills behind the event centre, the bike course will take riders along the ridge toward the River Wye. You will then hug the river as you meander down the sensational Wye Valley towards the spectacular and historic Tintern Abbey. From here you will cross back over the River Wye and climb up the main climb of the course to the ridge. You will then head South East back to the Event Centre. The final 5 miles are gently downhill allowing time to recover before the Run.


Off the Bike, trainers on… and an off road run based on local tracks and footpaths. The running course winds it way around the stunning quarry and through nearby forest tracks in a circular loop. The opening mile of the course is uphill followed by a flat middle section and the all important downhill finish.

The Finish

A warm welcome and a Finishers Medal awaits; this completes a truly memorable event.

Overnight accommodation is available before or after the event in our Wooden Wigwam Cabins. With a range of wigwams to suit all budgets, you can experience a touch of luxury in the great outdoors at an unbeatable price.

Scuba Santas 2015 – Saturday 5th December at the NDAC

November 18, 2015

Scuba Santa at the National Diving and Activity Centre Chepstow

Saturday 5th December 2015, at the
National Diving & Activity Centre (NDAC), Chepstow

Scuba Santas will be entering its 9th year in 2015 and continues going from strength to strength. Often quoted as the “best dive of the year”, the event has raised thousands of pounds the RNLI and DDRC Healthcare whilst breaking its own world record several times over in the process.

Raising Money for the RNLI & DDRC HealthcareEach year, around Christmas time, we dress up in Santa costumes and go diving for fun and to raise money for charity. The money that we raise is shared between two great charities who provide a lot of support to divers – the RNLI and DDRC Healthcare (previously called the Diving Diseases Research Centre).

For the past few years the event has been held at the National Diving & Activity Centre (NDAC) near Chepstow, providing an easily accessible location for divers to get together for some festive diving fun!

‘Scuba Santas’ was founded by a group from Yorkshire Divers and was organised for many years by Lloyd Watkin. In 2013 & 2014 DDRC Healthcare, the diver health charity which answers all calls to the National Diver Accident Helpline, came on board to support Lloyd as ‘Scuba Santas Little Helpers!’. This year the event is being arranged by the National Diving & Activity Centre.

JOIN US this year for the 9th Annual Scuba Santas event on SATURDAY 5th DECEMBER 2015 at the NDAC.

This year Scuba Santas are aiming to attract between 100 and 200 Scuba Santas, and to raise well over £2,000 for our two charities.

In 2009 we set the World Record for ‘Most Scuba Diving Santas’ with 158 fabulous Scuba Santas. in 2013 Vobster Santas had 175, so the gauntlet has been laid down… are you up for the challenge this year?

Over £20,000 raised for Charity so far…

In 2007 we raised a few hundred pounds for the RNLI with 8 participating Santas, a Viking, a snowman, and a fairy! By the 2012 event we passed the amazing milestone of £20,000 and we have motivated people to start similar events all over the world since.

Not only is this a great advert for British scuba diving, it provides much needed funds for two great charities, and despite the chilly temperatures helps to get some grumpy people smiling and feeling festive!

Scuba Santas have some fantastic sponsors every year who donate some amazing prizes for our prize draw, helping to raise more money for our chosen charities. We also raise money through sponsorship of the event and sponsorship for individual Scuba Santa participants. Please support us and give generously! 50% of money donated goes to the RNLI and 50% to DDRC Healthcare.

If you want to join this fantastic event, sponsor Scuba Santa, donate a prize or just wish the Scuba Santas well, please do not hesitate to get in touch with Scuba Santas or follow them on their various social media sites. HO HO HO!!!
