Aged 61, Donald won the vintage category in yesterday's Midlothian Triathlon in Dalkeith and came 65th overall.
The event consisted of a 750m swim, 20km on the bike and a 5k run.
Donald wasn't the only MAC person there. At the tender age of 41, Scott Marriott completed his first triathlon, finishing 13th in the vets' category and 36th overall.
As Scott put it: "Not bad for a first outing in the dreaded water."
The T&F members were joined by a clutch of road runners who showed their mettle in some "foreign" events.
Have a look here at the full set of pics, taken by Alex Barr and John McCluskey and you'll spot at least one road runner striking a very unfamiliar pose.
Talking of pictures, the one on the right of John and Benny is another candidate for a caption competition.
Alex has penned some thoughts from the day here.
Results will appear here on the Scottish Athletics website.
Jo Clark is after your money again, as a down-payment for next year's Running The Highlands weekend.
The dates are Friday February 19 - Sunday February 21 and Jo's looking for deposits of £30 per head towards the total cost of £198 per person, based on a minimum of 18 people going.
You can read more details about the weekend here.
You can give Jo cash or a cheque at training over the next few weeks or email her for her home address or bank account details if you want to transfer the money online.
The possibilities for fun with this picture are endless. How about a caption like: "Three of Motherwell AC's sirens, snapped during a recruitment drive to find young new talent for the club"?
Or: "Guess which gleaming white smile in our picture is brought to you by Steradent"?
The truth is that being a member of MAC isn't just about grinding out the miles on muddy trails or on the track at Wishaw.
From time to time, it involves letting one's hair down (for those who still have it to let down).
On this occasion, it was a trip to Pivo Pivo in Glasgow for a slightly belated celebration of Jane Wedlock's 40th birthday and to introduce her and other members to the strains of Harry Margolis and his big band sound.
John Hughes delights in recounting how Harry was a fixture of the Glasgow music scene three or four decades ago and whose catchphrase "Get the polis, it's Harry Margolis" appeared on the sides of corporation buses.
As soon as Harry heard that MAC folk were in town and it was the big 40 for one of them, he was in like a shot, even though he struggled to get June, sorry, Jane's name right. And all this happening right under husband Michael's nose.
The raspberry beer seemed to be as big a hit with the ladies as was old Harry, causing one MAC stalwart to tiptoe unsteadily up the stairs at Pivo Pivo and head towards Cafe Gandolphi in search of more of the same.
As Wallace said to Gromit: "A grand day out!"
It was lucky for some of the 13 Motherwell AC runners who entered the Glasgow Women's 10k today.
Clare Barr ran a course best of 45.29, down 44 seconds on her previous fastest time round the city course.
Susan Moran, daughter of Fiona Moran, joined the club on Saturday and ran her first 10k, finishing in 52 minutes.
The other MAC entrants were Jane Wedlock, Phyllis Hands, Mae McIsaac, Elaine Jamieson, Elizabeth Martin, Fiona Moran, Jo Clark, Lesanne Cherry, Tracey Lamont, Laura McTavish and Carole Munro.

Mhairi Hendry provided a ray of sunshine at a rain-sodden Wishaw track by winning the u15 girls' 800m event in the Scottish Athletics u15/u17 Closed Championships yesterday.
Mhairi, pictured receiving her medal during a brief spell later in the afternoon when the sun was shining, took the title in style, recording a PB of 2.19.34.
She upped her game considerably in the final, after clocking 2.25.80 in the qualifying heat.

The results have been published for the Kintyre Way Relay, which was won by a six-strong MAC team.
They show that Russell McCoull, Alan Tait and Jo Clark broke the records for their respective legs of the 66-mile course.
As well as the individual legs records, the team set a new course record.
The full results are here.

Nearly 20 members took part in today's guest run in the sun in Peebles.
The 7.27-mile route was produced by John Hughes, who helpfully handed out several maps at the start in case he forgot the way.
There was a debate before the start about whether or not John had lured unsuspecting club members to Peebles to coincide with the Three Bridges race which took place there this afternoon.
William Martin seemed most keen to take part in the race but the deciding factor was that he hadn't brought a MAC top.
After establishing that the guest run was the summit of the group's ambitions for one day, it was off along the River Tweed for a very pleasant and easy-going run, including a steepish hill near the end just to add in a bit of hill work.
More pictures here.
The club is always open to suggestions for guest runs so please offer up any ideas you may have.
A very big congratulations goes to the MAC team which entered the Kintyre Way Relay today - and won!
The team was made up of Alex and Clare Barr, Jo and James Clark, Russell McCoull - running again only a week after his 53-mile Highland Fling ultra-marathon, and Alan Tait.
The route totalled 66 miles from Tarbert to Campbeltown along the Kintyre Way on terrain ranging from hill paths and forestry tracks to beaches and seaside rocks.
The Motherwell six completed the course in 9hrs 41minutes with Jo bringing home the bacon on the last leg, in which she covered the 14 miles in 1hr 46minutes.
They rounded off the day with a ceilidh and presentation. Pictures to follow.
The results have been posted for the Central and South of Scotland League match at Linwood on April 27.
The male results are here, the female results here and the scrutinised scores are here.
