Our September 13, 2020 race did take place thanks to a permit and insurance cover from BTF and the positive and helpful attitude from everyone involved! So we hope to be able to repeat that race format in 2021. Please note that due to the school premises being booked up on Sundays in March the first race on the calendar for 2021 is on a SATURDAY.

The event 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.

Race route and transitions

To download the bikeroute - see duathlon_map1.pdf

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 accomodate 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 alongside The Pavilion, where showers, changing and refreshments will be available!

    Sri Chinmoy Tri Club's GO TRI DUATHLON, Tockington, 13.09.2020
    Time-trial start at the GO TRI duathlon, Tockington

    It was great to be hosting a race again after such a long time, and thanks are due to British Triathlon for insuring & permitting the event through the GO TRI initiative, Tockington Manor School for letting us use their facilities, the Sri Chinmoy Marathon Team for marshalling and of course The Athletes who came and took part.

    Turnout was lower than usual at 35 starters, but in these uncertain times that was actually above our expectations. We had a really broad range of ages and abilities as usual, which is what GO TRI is all about. It was a mix of familiar faces and first timers too.

    In the women's field of 15 the honours went to Tamsin Chick who came first in 47:10, Sally Sims who came second in 48:05 and Megan Edwards, third with a time of 48:35.

    The men's race was probably our best ever in terms of quality, with four athletes breaking the 40 minute barrier. First place went to Adam Whittaker who smashed the previous course record by more than 40 seconds, finishing in 36:33. Chris Mills came second in 38:38 while only 6 seconds separated third and fourth place - Robert Sims (39:13) and Wayne Williams (39:19).

    This race was very different to normal, with a time-trial start meaning everyone was competing against the clock without any clear idea of where they were in terms of position until everyone had finished and the final calculations had all been done. They call this format "the race of truth" though, so I hope everyone was happy with their result after racing against themselves. Thanks again to our competitors who all co-operated with the distancing and other health measures so that the event could go smoothly.

    We missed having a public reading of the results and applauding our winners, but we do have small trophies for the first man and first woman so these will be delivered soon.

    Photos will appear in our gallery ( - scroll down to the Bristol page) in the next day or two and the full provisional results are attached.

    We hope to hold a full series of 4 GO TRI events in 2021 so please keep an eye on our website for updates.

    GO TRI Autumn Duathlon Results 2019

    45 aspiring duathletes gathered at the startline today in excellent racing conditions. Winds were light enough for a few at the sharp end of the race to sport full disk wheels, while other athletes took on the challenge with mountain bikes & tourers. Unfortunately, roadworks in the first couple of KMs of the bike course meant we had to contend with a set of traffic lights (next to Duckingham Palace, for those who know the route) and this brought a large element of luck into the equation - some breezed through on green while others had to stick a foot down and wait for a minute for the lights to change. Times were still impressive with Chris Mills winning once again in 39.31 and 2nd and 3rd places going to Wayne Williams (40.44) and Robert Sims (41.27). The women's race was won by Sarah Gillies (48.30) ahead of Sally Sims (49.17) and Emma Ulmann (49.27). The attached full results are provisional so please get in touch if you notice any errors or omissions. Photos are at . Thanks to Tockington Manor School for hosting our race series in 2019 - see you all next year for more of the same!

    GO TRI Summer Duathlon Results 2019
    Sri Chinmoy GO TRI Duathlon Tockington Manor June 2019

    With a stiff breeze blowing over the levels we weren't expecting super-fast times at today's GO TRI but all our participants were on good form, with quick finishes right through the field and our first finisher only a few seconds off the course record. We don't have many athletes going under 40 minutes on this course but today Wayne Williams (39.51), Alex Tedd (39.21) and overall winner Joe Prichard (37.19) all broke through that barrier, with Joe narrowly missing out on Matt Fratesi's record of 37.15. In the women's race less than 2 minutes separated the top 3, with Katie Jones finishing in 49.49, second place Lucy Gardner in 48.52 and overall winner Sarah Gillies in 48.05. Lucia Gaetani came in with an overall time of 79 minutes but don't be fooled - she did some serious extra mileage on the bike course!

    Thanks to everyone who took part and to our team of only 6 marshals who made the whole event happen. Our next events are a 2 mile race this coming Tuesday (Eastville Park, Bristol, arrive by 7pm for 7.30 start) and our famous 3 x 1 mile relay two weeks later at the same venue. The relay has categories for clubs, unaffiliated runners (not club members), veteran teams (all 50+) and family teams (all 3 must be related) so if you can muster 3 runners to do one mile each, why not make up a team? There's a free ice cream for all finishers in that race too.

    Our last GO TRI event is another Tockington Duathlon in September and there are still a handful of places available for online signup via the British Triathlon website.
