Eleven athletes who represented Scotland at last year's Commonwealth Games will take part in Sunday's Senior Indoor Championships in Glasgow.
All are seeking good performances and championship medals at the Emirates Arena with the British Indoors event looming in Sheffield in a fortnight.
Inverness's Rachael Mackenzie will defend the women's high jump title she won at last year's event.
And Edinburgh's Sarah Warnock is favourite in the women's high jump.
The pair are joined by fellow Glasgow 2014 athletes Ray Bobrownicki, David Smith (both high jump), Zoey Clark (60m and 200m), Kirsty Yates, Chris Bennett, Angus McInroy (all shot put), Greg Louden (200m and 400m), Grant Plenderleith (200m) and Jade Nimmo (60m hurdles, high jump).
Sunday's Senior Indoors event culminates another busy weekend of activity in Scotland with more than 500 Masters athletes gearing up for their National XC at Kilmarnock on Saturday and a track and field championship the same day at the Emirates.
High jumper Bobrownicki, 30, was the Scotland pick for the Glasgow International last weekend, where he finished second at 2.19m.
But on Sunday he could face a real challenge from David Smith and Euro Under-23 bronze medallist Allan Smith, with the latter having jumped 2.24m recently in France.
"I don't know exactly who will be there on Sunday and I'm not going to think about it too much,' said Bobrownicki, who was champion in 2014 at 2.17m and finished ninth in the Commonwealth Games final at Hampden.
"I prefer to focus on those elements that I can control and on the performance itself, as those things never change.
"If I can continue to build upon what I did in the International, then I'm excited to see what will happen at the Scottish Senior Indoors and beyond."
With Kilbarchan's Jack Lochans and Lasswade's Robert Ferguson also both on the start-list, there could well be five Scottish men jumping over 2m on Sunday.
Discus thrower McInroy from Helensburgh and Glasgow hammer thrower Bennett will try their hand at the shot put, where Glasgow 2014 finalist Yates is a strong favourite for the women's gold.
Elsewhere in the field events, Peter Muirhead and Sam Adams won Scotland vests in the Sainsbury's Glasgow International match and will look to impress in the men's long jump and pole vault respectively.
On the track, there will be plenty of attention on the sprints with a couple of visiting athletes threatening to be in contention for medals.
Northern Irish international Amy Foster will challenge Kathryn Christie and Clark in the 60m while the likes of Ryan Oswald, Cameron Tindle, Tom Holligan, Plenderleith and Louden could make the podium.
The men's 400m looks like a straight fight between three of the Scotland 4x400m quartet from last weekend as the start list features Louden, Pat Swan and David Martin. The women's 200m could be one of the better races on the day with the contenders set to include Christie, Clark, Stacey Downie, Beth Dobbin, Alisha Rees and Chloe Lambert.
Katy Brown and Myles Edwards would love to add championship success to the Scotland vests they won last week at 800m and 1500m respectively but the likes of Mhairi Hendry and Grant Muir will seek to deny them those golds.
