Really pleased with this as started later in evening rich was on xbox so started a bit disjointed no real rhythm as couldnt focus totally but got into it.....about 3000m out was considering switching to 30minute 7000m workout as was rowing well but a little bit too much time to make up but carried on pushing for a quicker 12000m time....no real aches, fingers a little sore but dried them regularly....finished last 200m v quickly.
