Our GO TRI Duathlon is aimed at people training for a triathlon who want multisport practice, or anyone who wants the challenge of combining two sports in a fun race! There will be a limit of 50 people taking part to keep the course uncrowded and to stay in line with the aims of the GO TRI initiative which is focussed on small, low-cost races.

COVID-19: restrictions are no longer in place, so we plan to resume a pre-race briefing, teas/cakes in the Pavilion and announcement of the winners after the race. Anyone wishing to remain covid-cautious is welcome to take part and will be able to collect their race number outside & stay clear of others on the spacious course.

Upcoming Races

Race route and transitions

2023 - we are planning to relax the covid restrictions of recent years, but the race is naturally pretty covid-safe anyway. On arrival each athlete will park in the School car park, bring their bike and kit down the road to the Pavilion and pick up their number from the terrace facing the sports field. After that, please stow your bike in the transition area making sure that you will have 2m clearance from the athletes alongside. You should minimise the time you spend setting up your bike/kit (5 mins max please). Toilets are in the Pavilion, there's no need to gather in the main room while queuing (only one person in the main room at a time, others queue outside). There is no high-security bag storage but bags can be left on the terrace and the Race Director will be happy to look after car keys if required - just mark these with your name before handing them over e.g. using a label or tag.

The run route is detailed below:

RUN - 2KM - The run course takes in 3 laps of the sports field alongside our race HQ, The Pavilion at Tockington Manor. The entire course is flat and on grass - we recommend running shoes with a bit of grip if you have them.

TRANSITION - after completing the run, athletes will pick up their bike (bikes will be stored leaning against the fence, there is no specialist "racking") and wheel them 100m or so to the exit, where they will mount up before taking the left turn (supervised by a race marshal in case of any passing traffic) on to the road.

BIKE - 15KM - From Tockington the course is approx 15km (9 miles) on predominantly flat lanes and B roads through Pilning. On a Sunday morning there should be hardly any traffic on most parts of the course, but riders will be expected to obey the highway code and ride safely at all times. Some parts of the course are narrow and winding and riders may have to slow down to accommodate oncoming vehicles - other parts are wide enough for you to get some decent speed up. There are a couple of slopes but nothing I would call a "hill". There are two right turns on the course, both of which are marshalled. At all other points the course is well signed. A sweep vehicle containing a first aider and a bike mechanic will follow the riders in case anyone needs assistance. Please note that "bunch riding" is not permitted in this event - riders will be expected to ride separately and leave space between themselves and the rider in front, except when overtaking.

SECOND TRANSITION & FINAL RUN 2KM - after completing the bike course, riders will push their bikes back to the transition area, lean them back against the fence and complete another flat, 2KM run around the field, this time in the opposite direction. The finish line will be between the GO TRI banners at the  bottom of the field, please ensure your race number is clearly visible as you approach the finish, thanks!

    Results September 11 2022

    There were 31 athletes in Sunday's GO TRI Duathlon at Tockington.

    Conditions were pretty good - cool and dry without too much breeze - but some disruption to the route (roadworks) and the usual post-rain gravel on some of the turns meant it wasn't totally ideal. Nevertheless there were some fast times including a first place under 40 minutes (Chris Mills - 39.21). 2nd place went to veteran Mark Wilkinson (40.11), with Kit McColl 3rd (42.53). In the women's results, first overall was Marie Monaghan in a time of 44.23, with Gwenno Goode from Barry second in 48.18 and a 3rd place for Sarah Bennet in 50.15.

    Results are now online (see link attached) and I'm very happy to say that guest race photographer Nick Tuftnell has captured the event with a great gallery of photos on Flickr -  much appreciated Nick!  Thanks are also due to Lucinda from North Bristol Tri who stepped in as a marshal at the last minute so the race could go ahead.

    To those of you racing on our course for the first time I hope you enjoyed the simplicity of GO TRI and the scenic race route. We'll be fixing up our series for next year soon and hope to have three Duathlons as well as a GO TRI Triathlon all at the same venue in 2023.

    Duathlon Results 26 June 2022

    It was a small turnout again (seems to be the pattern as we all adjust to racing again post-lockdown) but definitely a case of quality not quantity, with everyone finishing under, or pretty much bang on, the hour. With blustery winds and 2 sections of gravel to negotiate as a result of road re-surfacing, that's an impressive set of times. Fastest in the men's line up were Chris Mills with an excellent winning time of 38:58, followed by Mark Wilkinson (40:20) and Pete Lloyd (42:22). We had a new winner in the womens's race, Odette Collett, who was racing on this course for the first time, with Sarah Bennett (50:20) and Victoria Brooke (50:41) in second and third. 

    There were excellent times all the way down the field, and we had what I believe is our biggest ever age range among the competitors, with youth represented by Chloe Shephard (16) and experience by Robin Drewett (81). 

    Attached are the results and a link to a photo gallery from the race.

    Thanks to everyone who took part and as always to our selfless team of marshals who put the race on - cheers everyone & see you in September for the next one.

    Sri Chinmoy Tri Club's GO TRI DUATHLON at Tockington, 3 April 2022

    It was our lowest ever turnout for the GO TRI event at Tockington, but that seems to be down to a combination of covid-uncertainty, sub-zero temperatures overnight and an unlucky prevalence of injuries hitting people just at the start of their racing season.

    Fortunately for the 21 brave souls who did make it to the start line, everyone got round without incident and the sun came out for pretty much the whole race.

    There were good times across the board (especially considering the need to ride cautiously on the shaded sections of the course which were still frosty) and worthy winners in Alex Brown (49:54) and Matt Washburn (43:14). Trophies will be on their way to the winners soon - congratulations to both.

    Our next Tockington event is the GO TRI Triathlon on June 2nd and our Eastville Park running events begin on 10th May, so hope to see you (and some warmer weather) soon.

    Results are in the attached PDF and photos will appear soon in our Race Gallery.
